[0036] Such as figure 1 As shown, the present invention proposes an image object co-segmentation method guided by local shape transfer, comprising the following steps:
[0037] (1) Image set preprocessing: Input M images containing objects of the same semantic category, use the saliency detection method proposed by Zhang et al. in 2015 to analyze the saliency of each image, and use the double mean of the saliency detection results Do the threshold to get the mask map, which is the initial segmentation result of the foreground and background, where the mask map is only composed of 0 and 1, 1 represents the foreground pixel point, and 0 represents the background pixel point.
[0038] (2) Perform dense feature point matching on any two images: for each image i (i=1,2,...,M), generate a 128-dimensional dense sift feature for each pixel on the image; The dense sift feature of picture i (i=1,2,...,M) and the dense sift feature of other pictures j (j=1,2,...,M and j≠i) adopt Kim et ...
