Description

Technical Field

[0001] The present invention relates to the field of Emoji emoticons, and in particular to a method and system for synthesizing note Emojis based on FFmpeg. Background Art

[0002] Emoji is a text-based pictographic symbol. It is different from pictures and emoticons. "Emoji" refers to pictures and "text" refers to characters. These characters can be used to represent a variety of expressions, such as a smiley face for laughter, a cake for food, etc. In the Internet age, Emoji is widely used to increase emotional expression, greatly enriching the lives and communications of Internet users.

[0003] In the field of Internet medicine, some health science notes are usually combined with text and Emoji emoticons to intuitively reflect the popular science content and enhance the expressive effect of the notes. However, due to FFmpeg's limited support for Emoji emoticon fonts and insufficient compatibility, some Emoji emoticons may not be displayed normally and the rendering quality is limited. Therefore, an effective method is needed to solve this pain point. The Emoji emoticons in the text are seamlessly embedded into the note pictures through image mapping using FFmpeg, so that Emoji emoticons can be added to the note pictures, thereby enriching the note content, solving the problem of emoji compatibility in different environments, and ensuring the stability and reliability of the note pictures. Summary of the invention

[0004] The main purpose of the present invention is to disclose a method and system for synthesizing note Emoji based on FFmpeg, which can easily add Emoji emoticons to note pictures and display them completely, thereby enriching the note content, solving the problem of Emoji emoticon compatibility in different environments, and ensuring the stability and reliability of note pictures.

[0025] Figure 1 It is a flow chart of a method for synthesizing note Emoji based on FFmpeg in an embodiment of the present invention;

[0026] Figure 2 It is a structural diagram of a system for synthesizing note Emoji based on FFmpeg in an embodiment of the present invention. DETAILED DESCRIPTION

[0027] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention more clearly understood, the spirit of the contents disclosed by the present invention will be clearly explained with the accompanying drawings and detailed descriptions below. After understanding the embodiments of the contents of the present invention, any technician in the relevant technical field can change and modify the techniques taught by the contents of the present invention without departing from the spirit and scope of the contents of the present invention.

[0028] Figure 1 A flowchart of an implementation method of a method for synthesizing note Emoji based on FFmpeg provided in an embodiment of the present invention, such as Figure 1 As shown, the method includes:

[0029] S1, receiving a note text with Emoji emoticons.

[0030] In this embodiment, the content of the note text includes but is not limited to medical field knowledge.

[0031] S2, identifying and extracting the Emoji emoticon, and marking the location information of the Emoji emoticon in the note text.

[0032] In this embodiment, the Emoji emoticons are recognized, then extracted and spaced, and the Emoji emoticons are stored in order. Preferably, according to the layout logic of the note text, the coordinate position of the Emoji emoticon in the note text is calculated, and the coordinate position includes the left spacing and top spacing of the Emoji emoticon in the note text.

[0033] Specifically, each font is represented by a square, that is, the width and height are the same, and 1 text is measured in 1 px. First, calculate the number of lines of text in the note and the number of words in each line. If it exceeds, the text size is adaptively reduced. Assuming that the Emoji emoticon is in the Nth line, use the x-axis and y-axis to represent the position of the Emoji emoticon, and calculate the position of the Emoji emoticon in the text:

[0034] x = left spacing + (number of words in a line * font size)

[0035] y = top spacing + (font size * N + (N-1) * line height)

[0036] Among them, the font size, line height, left spacing and top spacing can be set according to actual business conditions and are not limited in this application plan.

[0037] S3, matching the extracted Emoji emoticons with the Unicode encoding table to obtain the corresponding Emoji encoding, and finding the Emoji image corresponding to the encoding in the Emoji emoticon image mapping table.

[0038] In this embodiment, the Emoji emoticon has a specific encoding range and format in the Unicode encoding table, and the Emoji emoticon picture mapping table is a picture resource, and the Unicode encoding table and the Emoji emoticon picture mapping table are updated regularly. Specifically, assuming that the Emoji emoticon is represented by the code 1f60c in the Unicode encoding table, the corresponding Emoji picture is found in the Emoji emoticon picture mapping table according to the code 1f60c.

[0039] S4. Based on the location information, use FFmpeg to overlay the Emoji image into the note text to synthesize the note Emoji.

[0040] In this embodiment, FFmpeg-driven image synthesis is used to seamlessly embed Emoji images into note text. The converted Emoji image is accurately superimposed on the note text according to the previously calculated coordinate position through the overlay filter, so as to achieve a perfect fusion of expression and background content. After synthesizing the note Emoji, the note Emoji is quality checked, and the quality check includes at least one of color consistency, clarity, and alignment of Emoji images and note text. Among them, color consistency requires ensuring that the color mode of all images is consistent. In addition, after the note is synthesized, the entire note memory will become larger, and the image needs to be stretched or compressed, so the clarity needs to be guaranteed. Some Emoji images are relatively large, and if the reserved space is not enough, they will stick together with the note text. Therefore, it is necessary to layout according to the position information before synthesis to ensure that all elements are aligned.

[0041] According to an embodiment of the present invention, a system for synthesizing note Emoji based on FFmpeg is also provided. Figure 2 As shown, the system includes:

[0042] The receiving module 201 is used to receive note text with Emoji emoticons.

[0043] The recognition module 202 is used to recognize and extract the Emoji emoticon, and mark the position information of the Emoji emoticon in the note text. Preferably, in the recognition module, the position information includes the coordinate position of the Emoji emoticon in the note text calculated according to the typesetting logic of the note text, and the coordinate position includes the left spacing and top spacing of the Emoji emoticon in the note text.

[0044] The matching module 203 is used to match the extracted Emoji emoticons with the Unicode encoding table to obtain the corresponding Emoji encoding, and find the Emoji image corresponding to the encoding in the Emoji emoticon image mapping table. Preferably, in the matching module, the Unicode encoding table and the Emoji emoticon image mapping table are updated regularly.

[0045] The synthesis module 204 is used to use FFmpeg to superimpose the Emoji image into the note text according to the location information to synthesize the note Emoji.

[0046] Preferably, a quality inspection module 205 is also included for inspecting the synthesized note Emoji.

[0047] In summary, with the help of the above-mentioned implementation methods provided by the present invention, a method and system for synthesizing note Emoji based on FFmpeg are disclosed, which can easily add Emoji emoticons to note pictures and display them completely, thereby enriching the note content, solving the problem of Emoji emoticon compatibility in different environments, and ensuring the stability and reliability of note pictures.
