[0040] The embodiments of the present application will be further described below with reference to the accompanying drawings.

[0041] As Figure 1 shown, Figure 1is a flowchart of a presentation conversion method provided by an embodiment of the present application. The presentation conversion method includes but is not limited to the following steps:

[0042] In step S110, a to-be-converted presentation, a target document style label, and a plurality of first template pages are acquired.

[0043] In step S120, style recognition processing is performed on each first template page to obtain a first document style label of each first template page, and the first document style label is compared with the target document style label. According to a comparison result between the first document style label and the target document style label, a second template page is determined from the plurality of first template pages.

[0044] In step S130, image recognition processing is performed on the to-be-converted presentation to obtain first object information of the to-be-converted presentation, and image recognition processing is performed on each second template page to obtain second object information of each second template page.

[0045] In step S140, the first object information and the second object information are matched. According to a matching result between the first object information and the second object information, a target page is determined from each second template page.

[0046] In step S150, a target presentation is generated according to the first object information and the target page.

[0047] It can be understood that the user input is obtained the to-be-converted presentation and the target document style label, the target document style label is one of a plurality of preset document style labels, the document style label is used to represent the document style of the presentation, and a plurality of first template pages stored in the template library are obtained. The identification object of the style identification processing includes but is not limited to: the size of the presentation, the text features and picture features in the presentation. Through the style identification processing, the document style of each first template page can be effectively determined, combined with the preset document style label, the first document style label of each first template page is obtained, then the first document style label same as the target document style label is screened out, and then the first module page matched with the target document style label is taken as the second template page. All second template pages meet the document style requirement, then through image recognition processing on the to-be-converted presentation, first object information is obtained, and image recognition processing is performed on each second template page to obtain second object information. The first object information and the second object information refer to the sum of the feature information of each object in the presentation. The sum of the feature information of each object can be used as the feature information of the presentation. The object includes but is not limited to: text and picture; then the second object information with the highest matching degree with the first object information is determined, and the second template page corresponding to the second object information is taken as the target page, and then the target presentation is generated through the first object information and the target page; since the target page is the second template page closest to the feature information of the to-be-converted presentation, it can avoid large changes in the content of the to-be-converted presentation during the conversion process, increase the readability of the target presentation, and improve the conversion quality of the presentation; based on this, the first document style label of each first template page is identified by using the style identification processing, the first document style label and the target document style label are compared, and the second template page meeting the document style requirement is determined according to the comparison result, then the first object information of the to-be-converted presentation is identified by using the image recognition processing, and the second object information of each second template page is identified, then the first object information and the second object information are matched, and the target page suitable for converting the to-be-converted presentation is determined according to the matching result, and then the target presentation is generated, which realizes the conversion of the to-be-converted presentation into the target presentation, improves the conversion efficiency of the presentation, and reduces the time cost.

[0048] It is worth noting that the target presentation is generated by the first object information and the target page, and the specific steps include but are not limited to: removing the text content of the text box in the target page, and removing the picture in the target page, then adding the text content corresponding to the first object information into the corresponding text box in the target page, setting the text style of the text content to the text style in the initial state, and the text style includes but is not limited to: font, font size, text color, and text highlighting; then insert the picture corresponding to the first object information into the position of the picture in the initial state of the target page, and adjust the size of the picture corresponding to the first object information according to the size of the picture in the initial state of the target page.

[0049] It should be noted that the style recognition model can be used for style recognition processing. The presentation is input into the trained style recognition model. First, the pre-processing layer of the style recognition model is used for pre-processing, so as to determine the size of the presentation, the text features and picture features in the presentation; then, the style recognition model analyzes the size of the presentation, for example, the aspect ratio of the presentation is used to determine the display style of the presentation, the presentation with an aspect ratio greater than one is suitable for computer end, and the presentation with an aspect ratio less than one is suitable for mobile phone end; then, the style recognition model analyzes the text features in the presentation, for example, the text features include but are not limited to: text position, text word count and text font, the text font includes but is not limited to: Song, Kai and Cursive, first determine the text paragraph with the most text word count, then determine the text font of the text paragraph, and determine the font style of the presentation through the text font; then, the style recognition model analyzes the picture features in the presentation to determine the picture style of the presentation, and the picture style includes but is not limited to: technology, ink, business and cartoon, and the picture features include but are not limited to: picture position and picture size; the layout style of the presentation is also determined by the text position, text word count, picture position and picture size, and the layout style includes but is not limited to: graphic-text layout style, contrast layout style and clause layout style; the presentation style label is determined by the display style, font style, picture style and layout style of the presentation.

[0050] It should be noted that the presentation style label and the plurality of presentation training presentations are used as training data to train the preset classification model, so as to obtain the above-mentioned style recognition model.

[0051] It should be noted that the presentation refers to PPT, and can also refer to a poster or other design scheme with text content on the picture, which is not limited here.

[0052] In specific practice, the presentation conversion method can convert the presentation style of the to-be-converted presentation according to the template pages of different presentation styles, so as to meet the user demand and present the content in different styles. The presentation conversion method can be applied in the fields of education, training, design and the like.

[0057] It can be understood that the first text attribute information and the second text attribute information can be determined through optical character recognition, and the first image attribute information and the second image attribute information can be determined through image recognition. The first text attribute information and the second text attribute information both include but are not limited to text position information and text word number information. The first image attribute information and the second image attribute information both include but are not limited to picture position information and picture size information. The layout type of the to-be-converted presentation can be determined through the first text attribute information and the first image attribute information. The layout type of the second template page can be determined through the second text attribute information and the second image attribute information. The first layout type information is used to represent the layout type of the to-be-converted presentation, and the second layout type information is used to represent the layout type of the second template page.

[0058] It is worth noting that the optical character recognition can be performed through an optical character recognition model, and the image recognition can be performed through an image recognition model. The method of performing optical character recognition through an optical character recognition model and the method of performing image recognition through an image recognition model are well known to those skilled in the art, and will not be described here.

[0063] In step S340, the second text content information is subjected to semantic recognition processing to obtain second semantic information.

[0064] In step S350, the text type of each second text attribute information is determined according to the second text position information, the second semantic information, the second font size value and the second number of words value.

[0065] In step S360, the second layout type information is determined according to the text type of the second text attribute information, the second text position information and the second picture position information.

[0066] It can be understood that the first semantic information and the second semantic information are obtained through semantic recognition processing, the first semantic information is used to represent the semantic content of the first text content information, and the second semantic information is used to represent the semantic content of the second text content information, the text type of the first text attribute information can be analyzed through the first text position information, the first semantic information, the first font size value and the first number of words value, and then the first layout type information is determined in combination with the first picture position information, in addition, the text type of the second text attribute information can be analyzed through the second text position information, the second semantic information, the second font size value and the second number of words value, and then the second layout type information is determined in combination with the second picture position information, and the layout types of the to-be-converted presentation and the second template page can be accurately analyzed.

[0067] It is worth noting that semantic recognition processing belongs to natural language processing, and the method of performing semantic recognition through a trained semantic recognition model is a well-known technology to those skilled in the art, and will not be described here.

[0068] In addition, in an embodiment, the text type includes at least one of the following: a main title type, a sub-title type, and a main text type.

[0072] It can be understood that in the same page of the presentation, the font size values of the main title, the sub-title, and the main text are sequentially reduced, and the number of words of the main title, the sub-title, and the main text content is usually sequentially increased, so that the text type can be analyzed by the font size value or the number of words. When the page of the presentation is provided with one main title, one main text, and one picture, the layout type of the presentation belongs to the picture-text type. When the page of the presentation is provided with one main title, two parallel sub-titles, two parallel main texts, and two parallel pictures, the layout type of the presentation belongs to the contrast type. When the page of the presentation is provided with one main title, multiple sub-titles, and corresponding main texts of the sub-titles, the layout type of the presentation belongs to the clause type.

[0073] In addition, with reference to Figure 4 In an embodiment, the step S140 in the illustrated embodiment includes but is not limited to the following steps: Figure 1 The step S140 in the illustrated embodiment includes but is not limited to the following steps:

[0074] The step S410 includes comparing the first layout type information and the second layout type information, and determining the same type template page from each second template page according to the comparison result of the first layout type information and the second layout type information.

[0075] The step S420 includes matching the first object information and the second object information, and determining the target page from each same type template page according to the matching result between the first object information and the second object information.

[0076] It can be understood that the second template page with the same layout type as the to-be-converted presentation is determined as a same-type template page, and then the first object information and the second object information of the same-type template page are matched to determine the same-type template page closest to the feature information of the to-be-converted presentation as the target page. The same-type template pages are filtered out first. In the matching process, the number of same-type template pages is less than the number of second template pages, which can reduce the number of matching processes. Compared with determining the same-type template page from each second template page, the matching process of the first object information and the second object information takes more time. Therefore, by reducing the number of matching processes, the matching efficiency can be effectively improved, and the conversion efficiency of the presentation can be improved.

[0077] As shown in FIG. 1, Figure 5 As shown in FIG. 1, Figure 4 The step S420 in the embodiment shown includes but is not limited to the following steps:

[0078] In step S510, the to-be-converted presentation and each same-type template page are merged to obtain a merged page corresponding to each same-type template page.

[0079] In step S520, for each merged page, a first matching value is determined according to the first text position information and the second text position information, and a second matching value is determined according to the first picture position information and the second picture position information.

[0080] In step S530, the matching result of each same-type template page and the to-be-converted presentation is determined according to the first matching value and the second matching value.

[0081] In step S540, the target page is determined from each same-type template page according to the matching result of each same-type template page and the to-be-converted presentation.

[0082] It can be understood that the to-be-converted presentation and each same-type template page are merged, which means that the content of the to-be-converted presentation is completely copied into each same-type template page to obtain a corresponding merged page. The first text position information and the second text position information are analyzed to calculate a first matching value representing the text matching degree, and the first picture position information and the second picture position information are analyzed to calculate a second matching value representing the picture matching degree. Then the first matching value and the second matching value are added to obtain a total matching value, which is the matching result of each same-type template page. The same-type template page with the highest total matching value is selected as the target page, which can effectively filter out the same-type template page closest to the feature information of the to-be-converted presentation, avoid large changes in the content of the to-be-converted presentation during the conversion process, increase the readability of the target presentation, and improve the conversion quality of the presentation.

[0083] In a specific implementation, the first matching value is determined by determining a first text coordinate of a center of the text box in which the text is located in a page of the presentation according to the first text position information, determining a second text coordinate of the center of the text box in which the text is located in the page of the presentation according to the second text position information, and then calculating a first Euclidean distance between the first text coordinate and the second text coordinate; the first matching value is negatively correlated with the first Euclidean distance, and the smaller the value of the first Euclidean distance, the greater the first matching value; the second matching value is determined by determining a first picture coordinate of a center of the picture in the page of the presentation according to the first picture position information, determining a second picture coordinate of the center of the picture in the page of the presentation according to the second picture position information, and then calculating a second Euclidean distance between the first picture coordinate and the second picture coordinate; the second matching value is negatively correlated with the second Euclidean distance, and the smaller the value of the second Euclidean distance, the greater the second matching value.

[0084] It is worth noting that the method of calculating the Euclidean distance of two coordinates is a well-known technology to those skilled in the art, and will not be described in detail here.

[0085] As shown in FIG. 6, Figure 6 As shown in FIG. 4, Figure 4 Before step S410 in the embodiment shown, the following steps are further included but not limited to:

[0086] Step S610, when the first typesetting type information is other type information, changing the first typesetting type information to graphic-text type information.

[0087] It can be understood that the first typesetting type information is other type information, which means that there is no first typesetting type information in the second typesetting type information. Changing the first typesetting type information to general graphic-text type information can ensure the effective conversion of the to-be-converted presentation.

[0088] In addition, with reference to Figure 7 The application further provides a presentation conversion device 700, comprising:

[0089] An acquisition unit 710 is configured to acquire a to-be-converted presentation, a target document style label, and a plurality of first template pages.

[0091] The recognition unit 730 is configured to perform image recognition processing on the to-be-converted presentation to obtain first object information of the to-be-converted presentation, and perform image recognition processing on each second template page to obtain second object information of each second template page.

[0092] The matching unit 740 is configured to perform matching processing on the first object information and the second object information, and determine a target page from each second template page according to a matching result between the first object information and the second object information.

[0093] The generation unit 750 is configured to generate a target presentation according to the first object information and the target page.

[0094] It can be understood that the specific implementation of the presentation conversion apparatus 700 is basically the same as the specific implementation of the presentation conversion method described above, and will not be repeated here. Based on this, the first document style label of each first template page is identified by using style recognition processing, the first document style label and the target document style label are compared, and the second template page that meets the document style requirement is determined according to the comparison result. Then, the first object information of the to-be-converted presentation and the second object information of each second template page are identified by using image recognition processing. Then, the first object information and the second object information are matched, and the target page suitable for converting the to-be-converted presentation is determined according to the matching result. Then, the target presentation is generated, the to-be-converted presentation is converted into the target presentation, the conversion efficiency of the presentation is improved, and the time cost is reduced.
