Problems solved by technology
Taking flat-panel displays as an example, not only the increase in size and resolution, but also the increase in frame rate is also the goal pursued by flat-panel displays. However, the frame rate of old movies is relatively low. If you watch them on a new high-frame-rate flat-panel display The old low frame rate video cannot reflect the smooth effect brought by the high frame rate flat-panel display
[0003] For this reason, in the related art, a method of segmenting the picture and performing template matching is proposed for image interpolation processing, but this technology is only applicable to the processing of a single frame rate video source, and there are two or more video sources in the video source. When the frame rate (for example, the video source contains both 25Hz and 30Hz frame rates), the obtained interpolation result will be abnormal, even worse than the video source.

The invention discloses an image interpolation method and device and a storage medium, and the method comprises the following steps: obtaining a first image and a second image which are images of two adjacent frames in a to-be-processed video source; according to the frame rate of the to-be-processed video source and / or an image source in the to-be-processed video source, respectively performing segmentation processing on the first image and the second image to obtain a plurality of first segmented images and a plurality of second segmented images; performing image interpolation processing on each first segmented image and the corresponding second segmented image to obtain a region interpolation image corresponding to each first segmented image; and performing synthesis processing on the region interpolation images corresponding to the first segmented images to obtain frame interpolation images of the first image and the second image. According to the image interpolation method, after the image is segmented according to the frame rate and / or the image source of the video source to be processed, image interpolation is carried out, the obtained interpolated image can make the video smoother, and then the watching experience of a user on the video can be improved.
Description
technical field [0001] The present invention relates to the technical field of video processing, in particular to an image interpolation method, device and storage medium. Background technique [0002] With the prevalence of consumer multimedia products, electronic devices related to imaging or display have become important industrial items, such as flat panel displays, digital cameras, and the like. Taking flat-panel displays as an example, not only the increase in size and resolution, but also the increase in frame rate is also the goal pursued by flat-panel displays. However, the frame rate of old movies is relatively low. If you watch them on a new high-frame-rate flat-panel display Old low frame rate movies cannot reflect the smooth effect brought by high frame rate flat panel displays. [0003] For this reason, in the related art, a method of segmenting the picture and performing template matching is proposed for image interpolation processing, but this technology is ...
