Area-of-interest detection method based on Kinect

The invention discloses an area-of-interest detection method based on Kinect. The area-of-interest detection method is used for solving the technical problem that an existing area-of-interest detection method based on an improved saliency map model is low in accuracy. According to the technical scheme, a Kinect3D camera lens is used for obtaining a two-dimensional RGB image and depth information; on the basis, the RGB image is used for extracting various visual features and establishing a multi-scale visual feature map; then the feature map and a depth map are fused to generate the saliency map, and a winner-take-all strategy is used for generating a two-value saliency map; finally, dilation is performed on the two-value saliency map to detect a final area of interest. The 3D image, generated by the Kinect camera lens, in a RGB-D format can be used for detecting the area of interest, wherein the area of interest is consistent with the result of perception through the human eyes. Under the same condition, the matching rate of the area of interest is increased to 91.2% from 82.5% in the background technology, which means the matching rate is increased by 8.7%, and the area of interest is automatically detected by the utilization of the method.
