The present disclosure relates to a method for detecting a region of interest in an image, a video encoding method, apparatuses, a computer device, a storage medium, and a computer program product. The method includes: obtaining a current to-be-detected image frame, determining a mapping block size parameter value from encoding parameters corresponding to the current to-be-detected image frame, dividing the current to-be-detected image frame to obtain multiple mapping blocks based on the mapping block size parameter value, performing a texture region detection on each mapping block to obtain a texture region of interest detection result. performing a motion region of interest detection on each mapping block to obtain a motion region of interest detection result, and determining a region of interest of the current to-be-detected image frame based on the texture region of interest detection result and the motion region of interest detection result.

Disclosed are parallel encoding and decoding method and apparatus, a computer device, a storage medium, and a computer program product. The method includes: acquiring a synchronization node corresponding to a codec core, and transmitting a frame synchronization detection request to the synchronization node based on a frame to be encoded and decoded; acquiring a frame synchronization result corresponding to the frame synchronization detection request; and determining a encoding and decoding mode for the frame to be encoded and decoded based on the frame synchronization result, and encoding and decoding the frame to be encoded and decoded based on the encoding and decoding mode. By using the method, a plurality of codec cores can be employed to code and decode different frames in the same video in parallel, thereby improving the frame rate.

Parallel encoding and decoding method and apparatus, computer device, and storage medium

An image compression method is provided. The image compression method includes steps of receiving, by a tile division generator, an input image; by the tile division generator, determining whether the input image corresponds to a partial updated region and whether the partial updated region coincides with one tile or a combination of tiles of a current frame and generating a determination result; and by the tile division generator, determining whether to re-perform tile division and compressing and encoding one portion of the current frame according to the determination result.
