Abstract

The invention relates to an image segmentation method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a target image and a segmentation pattern set; extracting a target segmentation style from the segmentation style set; obtaining a target segmentation block image based on the target segmentation pattern and the target image; in the reference image, performing integer pixel search on the target image and the target segmentation block image to obtain first motion estimation information between the target image and the reference image and second motion estimation information between the target segmentation block image and the reference image; inputting the first motion estimation information and the second motion estimation information into a target segmentation neural network corresponding to the target segmentation pattern to obtain a target segmentation result; and performing segmentation processing on the target image according to the target segmentation result. According to the technical scheme of the invention, the input information of the target segmentation neural network can be reduced, thereby reducing the processing complexity of artificial intelligence, and improving the coding efficiency.

Description

technical field [0001] The present application relates to the technical field of multimedia processing, and in particular, to an image segmentation method, apparatus, electronic device and storage medium. Background technique [0002] Now with the development of multimedia technology, encoders have attracted much attention, for example, H.264 / 265 / 266 encoders, but H.264 / 265 / 266 encoders require high patent fees in practical applications. Based on this situation, AOM Alliance (Alliancefor Open Media, Open Media Alliance) proposed the first generation of high-performance codec AV1 (aomediavideo 1) free of royalties, AV1 has more than 30% performance improvement compared to H.265 encoder, and compared to H.265 encoder The latest H.266 encoders also have only a 5-6% performance difference, and the complexity at the best performance of AV1 is no more than half the complexity of the best performance of H.266. Therefore, AV1 has received more attention in the industry, and there a...
