Abstract
The disclosure involves an image guided video semantic object segmentation method and apparatus, locate a target object in a sample image to obtain an object sample; extract a candidate region from each frame; match multiple candidate regions extracted from the each frame with the object sample to obtain a similarity rating of each candidate region; rank the similarity rating of each candidate region to select a predefined candidate region number of high rating candidate region ranked by the similarity; preliminarily segment a foreground and a background from the selected high rating candidate region; construct an optimization function for the preliminarily segmented foreground and background; solve the optimization function to obtain a optimal candidate region set; and propagate a preliminary foreground segmentation corresponding to the optimal candidate region to an entire video to obtain a semantic object segmentation of the input video.
