Title:
IMAGE SALIENCY DETECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2015/180527
Kind Code:
A1
Abstract:
Disclosed is an image saliency detection method, comprising the steps of: 1) conducting segmentation processing on an image to divide same into K image blocks with the size of M × N, where the values of M and N are set by a user; 2) calculating a characteristic value of each image block, the characteristic value comprising a brightness characteristic value, a colour characteristic value, a direction characteristic value, a depth characteristic value and a sparseness characteristic value; 3) quantifying various characteristic values of each image block to the same interval range, conducting fusion calculation on various characteristic values to obtain difference values between each image block and the remaining image blocks; and 4) determining a weighting coefficient, conducting weighted summation on the difference values between each image block and the remaining image blocks to obtain a saliency value of each image block. By introducing a depth characteristic and a sparseness characteristic based on the traditional characteristic value, the image saliency detection method of the present invention meets the characteristic of image observation by vision systems of human beings, thereby guaranteeing that saliency images obtained by processing meet the vision systems of human beings, and the saliency images are accurate.
