Embodiment Construction

[0046] The invention utilizes wavelet transform to model the visual multi-channel characteristics in the human visual system, and applies the model to the key frame to obtain a good stereoscopic video quality evaluation result. Experimental results show that the evaluation results of the stereoscopic video quality evaluation model proposed by the present invention are in good agreement with the subjective evaluation results, which can not only reflect human visual characteristics, but also accurately evaluate the quality of stereoscopic video.

[0047] The visual multi-channel model originates from the study of the lateral geniculate body in the human visual system. The study found that the human visual system transmits different frequency components in the scene perceived by the human eye through different neural channels. This is the so-called human Visual multichannel effects in the visual system.

[0048] In order to model the visual multi-channel effect, we should decompo...

Abstract

The invention belongs to the field of video and image processing, and provides a stereoscopic video objective quality evaluation method which is more suitable to the human vision system related characteristic and effective. A new stereoscopic video objective quality evaluation method can more accurately evaluate the quality of the stereoscopic video, and pushes the development of the stereoscopic imaging technology at the same time. An application method of a vision multichannel model in stereoscopic video quality objective evaluation comprises the following steps: modelling the vision multichannel model by use of haar wavelets, firstly performing three-level wavelet transformation on an absolute difference map of a key frame so as to simulate the human eye multichannel characteristic by resolving the absolute difference map into different directions and frequency ingredients; and evaluating the different components obtained through transformation by applying SSIM so as to obtain the corresponding objective quality; obtaining the single quality of each key frame by use of the wavelet inverse transformation; and finally weighting the quality of the key frame by use of the weight of the key frame so as to obtain the complete stereoscopic video quality. The application method of the vision multichannel model is mainly applied to the video and image processing.

Description

technical field [0001] The invention belongs to the field of video and image processing, and relates to the improvement and optimization of the stereoscopic image quality evaluation method and the stereoscopic video quality evaluation method, and the application of the multi-channel effect in the human visual system in the objective evaluation of the stereoscopic video quality. Application method of multi-channel model in objective evaluation of stereoscopic video quality. Background technique [0002] The Human Visual System can be regarded as an intricate and comprehensive information processing system. It is a key tool for human beings to recognize nature. Biologically, it is composed of a large number of nerve cells interconnected. By understanding the human visual system and its characteristics, we can better understand the process of human eyes watching stereoscopic video, so as to better evaluate the quality of stereoscopic video. [0003] With the in-depth research ...
