Embodiment Construction

[0064] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0065] A kind of stereo image quality objective evaluation method proposed by the present invention, its overall realization block diagram is as follows figure 1 As shown, it specifically includes the following steps:

[0066] ① Order S org Denotes the original distortion-free stereo image, let S dis means S org The distorted stereo image obtained after distortion, the S org The left view image of is denoted as {L org (x,y)}, the S org The right view image of is denoted as {R org (x,y)}, the S dis The left view image of is denoted as {L dis (x,y)}, the S dis The right view image of is denoted as {R dis (x,y)}, where (x,y) represents S org and S dis The coordinate position of the pixel in , 1≤x≤W, 1≤y≤H, W means S org and S dis The width, H means S org and S dis height, L org (x,y) means {L org The pixel value of the pixel who...

Abstract

The present invention discloses a stereoscopic image quality objective evaluation method. Response output after lateral geniculate nucleus processing of each pixel in each of a left viewpoint image and a right viewpoint image of an undistorted stereoscopic image and a distorted stereoscopic image, response output after primary monocular visual cortex processing, response output on different parallax planes after primary binocular visual cortex processing of pixels at the same coordinate position in the left viewpoint image and the right viewpoint image of the distortion stereoscopic image and pixels at the same coordinate position in the left viewpoint image and the right viewpoint image of the undistorted stereoscopic image, and response output on different parallax planes after second binocular visual cortex processing of the pixels at the same coordinate position in the left viewpoint image and the right viewpoint image of the distortion stereoscopic image and the pixels at the same coordinate position in the left viewpoint image and the right viewpoint image of the undistorted stereoscopic image are calculated, so as to obtain a quality vector of the distorted stereoscopic image. Through adoption of the method, the quality change of the distorted stereoscopic image can be well reflected, and a correlation between an objective evaluation result and subjective perception is effectively improved.

Description

technical field [0001] The invention relates to an image quality evaluation method, in particular to an objective evaluation method for stereoscopic image quality. Background technique [0002] With the rapid development of image coding technology and stereoscopic display technology, stereoscopic image technology has received more and more attention and applications, and has become a current research hotspot. Stereoscopic image technology utilizes the principle of binocular parallax of the human eye. Both eyes independently receive left and right viewpoint images from the same scene, and form binocular parallax through brain fusion, so as to enjoy stereoscopic images with a sense of depth and realism. . Due to the influence of acquisition system, storage compression and transmission equipment, stereoscopic images will inevitably introduce a series of distortions. Compared with single-channel images, stereoscopic images need to ensure the image quality of two channels at the...
