Problems solved by technology

[0003] The current objective evaluation method for stereoscopic image quality is to directly apply the planar image quality evaluation method to evaluate the stereoscopic image quality. Features (for example, 3D visual attention) are not simple extensions of plane visual features. How to effectively extract stereoscopic features in the process of stereoscopic image quality evaluation and fuse the evaluation results so that the objective evaluation results are more in line with the human visual system, Both are problems that need to be studied and solved in the process of objective quality evaluation of stereoscopic images

Abstract

The invention discloses a three-dimensional picture quality objective evaluation method based on three-dimensional visual attention. The method comprises the steps of respectively calculating an original undistorted three-dimensional picture one-eyed figure and an one-eyed figure of an anamorphic three-dimensional picture to be evaluated; calculating significant figures of the two one-eyed figures and an off-centering figure, a foreground figure and a background figure of the original undistorted three-dimensional picture one-eyed figure; obtaining a three-dimensional visual attention image, and merging objective evaluation metric values of all pixel points in the one-eyed figure of the anamorphic three-dimensional picture to be evaluated, and obtaining a picture quality objective evaluation predicted value of the anamorphic three-dimensional picture to be evaluated. The three-dimensional picture quality objective evaluation method based on the three-dimensional visual attention has the advantages that the obtained three-dimensional visual attention image can well reflect influence of space three-dimensional vision information to attention, and an objective evaluation result can be better fit with human vision, so that relevancy of the 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 of stereoscopic image quality based on three-dimensional visual attention. 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 binocular parallax principle 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 a stereoscopic image 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 th...
