Embodiment 1
[0066] Embodiment 1, a method for identifying a video format, such as figure 1 shown, including:
[0067] 200. Split the obtained image to be recognized into two split images from the midline; compare the characteristics of the representative images of the two split images obtained by splitting, and obtain the image feature difference of the two split images;
[0068] 300. Determine the display format of the obtained image to be recognized according to the obtained image feature difference of the two split images, for example, when the image feature difference satisfies a preset condition, identify it as a two-dimensional 2D format; when the image When the feature difference does not meet the preset conditions, it is recognized as a three-dimensional 3D format.
[0069] In this embodiment, the image feature difference includes the left and right image feature difference and the upper and lower image feature difference; the step 200 may specifically include:
[0070] The acqu...
Embodiment 2
[0124] Embodiment 2. A format recognition device
[0125] combine Figure 1 to Figure 5 The first embodiment shown, such as Figure 6 As shown, the format recognition device of this embodiment mainly includes a splitting module 610, a comparison module 620, and a judgment module 630, wherein:
[0126] A splitting module 610, configured to split the acquired image to be recognized along the midline to obtain two split images;
[0127] The comparison module 620, connected to the splitting module 610, is used to compare the characteristics of the representative images of the two split images, and obtain the image feature difference of the two split images;
[0128] The judging module 630 is connected to the comparing module 620, and is configured to determine the display format of the acquired image to be recognized according to the acquired image characteristic difference of the two split images.
[0129] The splitting module 610 is used to split the image to be recognized al...

Abstract
The invention discloses a format recognition method and device, aiming at the problem how to accurately judge the format of a video, an image and other files. The method comprises the following steps of: splitting an image to be recognized along a center line to obtain two split images; comparing the characteristics of the representation images of the two split images to obtain the image characteristic difference of the two split images; and determining the display format of the acquired image to be recognized according to the image characteristic difference of the two split images. By adopting the embodiment of the invention, whether a file is in a 3D format or a 2D format can be accurately judged, thus playing or displaying can be correspondingly carried out according to the file format when the video is required to be played or the image is required to be displayed.
Description
technical field [0001] The invention relates to the field of multimedia, in particular to a format identification method and identification device. Background technique [0002] With the continuous development of 3D (three-dimensional) technology, various sources of 3D formats have emerged; however, there is no unified format for current 3D sources, and the mainstream formats include top-bottom format, left-right format and other formats. . [0003] When a playback device plays an image or a video, it first needs to know what format the file is in; but at present, there are a large number of images or videos in 3D format and 2D (two-dimensional) format; when providing When the party does not identify whether the image or video is in 3D or 2D format, the playback device will not be able to accurately know its file format. Contents of the invention [0004] The technical problem to be solved by the present invention is how to accurately judge the file formats of videos, im...
