Problems solved by technology

The most accurate image quality evaluation is the subjective evaluation of human eye observation. However, subjective evaluation requires a lot of energy, manpower, time and money. Therefore, it is indispensable to develop an objective quality evaluation of stereoscopic images that simulates the subjective evaluation of human eyes.

Embodiment Construction

[0069] With reference to the accompanying drawings, a specific example is used to describe the process of realizing the objective evaluation of the stereoscopic image quality for the content of the present invention.

[0070] In the image quality evaluation, we continue to use the single-view image quality evaluation method: the objective quality evaluation method based on the visual importance model (VSSSIM), as shown in the attached figure 1 shown. We will evaluate the left image and the right image separately, first explain the separate evaluation of the left image, and the evaluation steps of the right image are the same as the left image. Firstly, the left image to be evaluated is corrected with evaluation image according to the JND value of its reference image, that is, the perceptual redundant part. The correcting steps are: if the pixel value is within the visibility threshold of JND, then the human eyes will not feel the distortion, then modify the pixel value of th...

Abstract

The invention provides an objective evaluation method for stereo image quality. A stereo image is finally presented to a user through acquisition, compression, storage, transmission, reconstruction and the like, and the original image has a distortion possibility in each link. Therefore, the quality of the image finally presented to the user needs to be evaluated objectively by a person, but such method of evaluating the quality artificially and subjectively consumes a plenty of manpower as well as time and high cost, and has no real-time performance. Aiming at the problems mentioned above, an objective evaluation method for the stereo image quality is provided.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to an objective evaluation method of stereoscopic image quality. Background technique [0002] Stereoscopic images have become a vast area of ​​research in recent years, driven by the entertainment industry and scientific applications. With the continuous development of stereoscopic technology, various 3D applications, such as 3DTV, are produced. The stereoscopic image transmission chain is composed of image acquisition, encoding and compression, network transmission, post-processing and display at the receiving end, etc., any stage of which may cause distortion of stereoscopic vision quality or an error in a certain step in the process of the transmission chain . Therefore, stereoscopic image quality assessment is a key factor in designing and optimizing parameters in stereoscopic systems. [0003] Objective quality assessment monitors image quality in a quality control syst...
