Abstract

The present invention relates to a multi-view video image segmentation method based on graph cut and view correlation, which belongs to the field of image processing. With the object to overcome the shortcomings seen in a prior method such as poor robustness, slow execution rate and unsatisfactory segmentation effect, a multi-view video image segmentation method is provided which comprises mainly two parts. An improved Grabcut algorithm is used to segment any single viewpoint image that is given. The introduced smooth item makes it easier to extract a target from the background and the measure to protect edge of the target ensures that the edge of an obtained target is still a smooth one. On the basis of the obtained target of viewpoint image, other targets of viewpoint images are extracted by view disparity matching and a morphological processing method. The algorithm adopts a segmentation method featuring stereoscopic targets matching and tracking in a super-pixel domain, improves the Slic super-pixel generation algorithm and redefines the energy function, which effectively raises the segmentation efficiency under the premise of ensuring a segmentation result with high accuracy and promises the algorithm for wide applications.

Description

technical field [0001] The invention belongs to the field of image processing, and relates to a multi-viewpoint image segmentation technology, in particular to a multi-viewpoint video image segmentation method based on graph cut and view domain correlation. Background technique [0002] With the continuous development of multimedia technology and the improvement of people's living standards, ordinary video can no longer meet people's visual needs. Different from ordinary video, multi-view video is an image sequence obtained by using multiple cameras to shoot the same scene from different positions. It can provide depth information of real three-dimensional world scenes, and has a stronger sense of three-dimensionality and realism, so it is very popular among people. . Object-based video technology has attracted extensive attention in stereoscopic image and video processing due to its advantages of good semantic awareness and interactive operation. Therefore, object-based s...
