Embodiment Construction

[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0048] Refer to attached figure 1 , the concrete steps of the present invention are as follows:

[0049] Step 1. Input the left and right viewpoint images in the stereo matching test image library.

[0050] Step 2. Image segmentation.

[0051] For the input left and right viewpoint images, the mean value shift is performed respectively to obtain the segmented images of the left and right viewpoint images, wherein, the specific steps of the mean value shift are as follows:

[0052] In the first step, the 2-dimensional coordinates of the pixel and the color information of the three channels of red, green, and blue are combined into a 5-dimensional spatial coordinate.

[0053] In the second step, a target point is arbitrarily selected in the left and right viewpoint images.

[0054] The third step is to construct a sphere with the selected target point as th...

Abstract

The invention discloses a parallax image correcting method based on the image segmentation and credibility and aims to solve the problem that the accuracy of a parallax image is low after the parallax image correction currently. The method includes 1, inputting left and right viewpoint images; 2, performing image segmentation through mean shift; 3, acquiring an initial parallax image by an adaptive weight stereo matching method; 4, detecting the credibility of the initial parallax image by means of the generated initial parallax image and the matching cost; 5, performing parallax correction on the basis of the initial parallax image and the credibility. By the aid of the method, the problem of an incorrect parallax value caused by the shielding effect is solved, the accuracy of parallax correction is improved, and the parallax image with completely-protected boundary information, natural structure and high accuracy.

Description

technical field [0001] The invention belongs to the technical field of image processing, and further relates to a parallax image correction method based on image segmentation and reliability in the technical field of video processing. The invention can effectively solve the wrong matching caused by the occlusion effect between images, improve the accuracy of the parallax image generated by estimation, and is used in the related fields of 3DTV and depth image rendering. Background technique [0002] In the digital age of information, ordinary 2D video can no longer meet the needs of human daily life and work in some aspects, and 3D video technology has become an important field of technological development. Among them, 2D to 3D technology can convert traditional flat video into stereoscopic video. This method is low in cost and strong in applicability. However, due to the limited depth information of the video itself, the resulting stereoscopic video effect cannot meet actual...
