Problems solved by technology

Among them, the commonly used method in the 2D-based evaluation method is to directly use the classic planar image quality evaluation method to evaluate the quality of the stereoscopic image. The biggest difference between the stereoscopic image and the planar image is that the stereoscopic image has a sense of depth and presence. However, this The method does not take i

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0024] A method for objective quality evaluation of stereoscopic images proposed by the present invention, its overall realization block diagram is as follows figure 1 As shown, the process is as follows:

[0025] Firstly, the second-order Riesz transformation is performed on the left and right viewpoint images of the original undistorted stereo image, and the left and right viewpoint images of the distorted stereo image to obtain the respective magnitude images and phase images . Secondly, the disparity image between the left viewpoint image and the right viewpoint image of the original undistorted stereoscopic image is calculated, and the disparity image between the left viewpoint image and the right viewpoint image of the distorted stereoscopic image to be evaluated is calculated. Again, according to the magnitude image and phase image of...

Abstract

The invention discloses a stereo image objective quality evaluation method. The method includes the steps that Riesz transformation is carried out on a left viewpoint image and a right viewpoint image of an undistorted stereo image and a left viewpoint image and a right viewpoint image of a distorted stereo image; a left and right viewpoint feature fusion image of the undistorted stereo image and a left and right viewpoint feature fusion image of the distorted stereo image are obtained by using the obtained respective amplitude images and phase images and parallax information; according to the two left and right viewpoint feature fusion images, an image quality objective evaluation value of the distorted stereo image is obtained, and as the characteristic of left and right viewpoint feature fusion is fully used, the correlation of objective evaluation results and subjective perceptions is effectively improved.

Description

technical field [0001] The invention relates to an image quality evaluation technology, in particular to an objective quality evaluation method of a stereoscopic image. Background technique [0002] Since the beginning of this century, with the maturity of stereoscopic image / video system processing technology and the rapid development of computer network and communication technology, people have a strong demand for stereoscopic image / video system. Compared with the traditional single-viewpoint image / video system, the stereoscopic image / video system is more and more popular because it can provide new visual experiences such as stereoscopic presence and viewpoint interactivity. Direction of development. However, in order to obtain better presence and visual effects, people put forward higher requirements on the perceived quality of stereoscopic images. Stereoscopic image quality is an important index to measure the performance of stereoscopic image / video system. In the ster...
