Embodiment Construction

[0020] The examples of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0021] The experiment carried out by the present invention is realized by programming on a PC test platform with a CPU of 2.39GHz and a memory of 2G.

[0022] like figure 1 As shown, the technical solution adopted by the salient object segmentation method in the stereoscopic image based on depth information and graph cutting in the present invention is: first input the original image and the depth map, perform image segmentation on the original image and the depth map, and then use the saliency The model generates a saliency map; then set a threshold on the saliency map to obtain object / background seed points to complete the initial segmentation of the original image; then use the depth map, the generated saliency map, and the saliency-weighted histogram to Construct a graph and design a cost function, and use the graph cutting method to auto...

Abstract

The invention discloses a salient object segmenting method in a stereo image based on depth information and image cutting. The method comprises: inputting and segmenting an original image and a depth map in order to acquire a plurality of areas; computing a saliency map of the original image in combination with area-class depths, colors, and spatial domain information; acquiring a threshold value of the saliency map obtained through computation in order to complete initial segmentation of the original image, thereby acquiring an object / background seed point; constructing a map by using the depth map, the saliency map obtained through computation, and a salient weighted histogram, and designing a cost function; and completing salient object segmentation at one time by using a maximum flow minimum cut algorithm. The method reasonably utilizes the depth information and the saliency map, and more accurately and automatically segment the salient object in the stereo image.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a salient object segmentation method in a stereoscopic image based on depth information and graph cutting. This method is mainly considered from the perspective of rational use of depth information and saliency map to improve the results of salient object segmentation. It aims to use depth, color and spatial information to generate saliency map, and then combine depth map and saliency weighted histogram. Graphs to build graphs and design cost functions to improve the results of salient object segmentation with graph cutting methods. Background technique [0002] Salient object segmentation technology refers to the separation of the object of interest to the user in the video or image from the background at the pixel level. In the existing segmentation technology, the saliency model can be constructed mainly by using information such as color, direction, and texture, and t...
