Abstract

The invention discloses an image significance detection method and device based on depth information. The method comprises the steps: acquiring a to-be-detected image and a depth image of the to-be-detected image; acquiring a feature image of the to-be-detected image, obtaining a first feature image, and acquiring a feature image of the depth image, and obtaining a second feature image; obtaininga significance image of the to-be-detected image based on the first feature image and the second feature image. The method and device solve technical problems that a significance detection algorithm is not high in precision in the prior art.

Description

technical field [0001] The present invention relates to the field of image processing, in particular to an image saliency detection method and device based on depth information. Background technique [0002] When people look at images, people always pay attention to a subset of the whole image, which is called visual attention. Visual attention is a neurobiological process that can filter out irrelevant information and highlight the most salient foreground information. . Various computational models, including saliency detection algorithms, have been developed to mimic this mechanism for active gaze control, recognition, segmentation, and image retrieval. In general, saliency detection algorithms can be divided into top-down methods and bottom-up methods, among them, top-down methods are task-driven and require supervised learning; bottom-up methods usually use low-level Hints, such as color features, distance features, and heuristic saliency features, among them, one of t...
