Saliency detection method and device based on RGB image pseudo-depth information

Abstract

The embodiment of the invention discloses a significance detection method and device based on RGB image pseudo depth information, and the method comprises the steps: carrying out the depth estimationof an RGB image, and obtaining the pseudo depth information; performing weighted average calculation according to the color features of the superpixels in the RGB image to generate a color contrast area; generating a depth contrast area by calculating the depth contrast between the superpixels in the RGB image; generating a texture contrast area according to the texture contrast between the superpixels in the RGB image; according to the color comparison area, the depth comparison area and the texture comparison area, carrying out the fusion calculation according to a preset significance fusionalgorithm, and outputting a significance detection result. By adopting the method provided by the invention, the saliency detection effect can be obviously improved, the operation complexity and costexpenditure are reduced, and the generalization ability and efficiency of carrying out saliency detection on the RGB image are improved.

Description

Technical field [0001] The embodiment of the present invention relates to the field of computer vision, in particular to a saliency detection method and device based on RGB image pseudo-depth information, and also to an electronic device and a computer-readable storage medium. Background technique [0002] In the field of computer vision, with the increase of various cameras and laser scanning equipment, saliency detection technology is increasingly applied in RGB image segmentation, object detection and recognition, etc. The purpose is to allow computers to simulate human vision recognition Function to find the most eye-catching local target from the visual scene. In the saliency detection technology, a good saliency detection model can accurately locate the salient target and retain the original RGB image information, so as to minimize the possibility of losing the actual salient area or marking the background as a salient area. [0003] Saliency detection, as a technology widel...
