Abstract

The invention discloses a virtual viewpoint quality evaluation method based on the visual masking effect, which fully considers the virtual viewpoint rendering distortion type and performs offset compensation on the virtual viewpoint image. The offset compensation process is aimed at special features such as virtual viewpoint rendering pixel point offset. Distortion, which effectively eliminates the impact of pixel position offset on the quality of the virtual viewpoint image, making the subjective and objective quality results of the virtual viewpoint image more consistent; fully considers the visual characteristics of the human eye, extracts the visually sensitive mask map of the reference image, and eliminates The influence of the distortion of the visually insensitive areas in the virtual viewpoint image on the objective quality evaluation results is made, so that the objective quality evaluation results are more consistent with the characteristics of the human eye; the distortion amplitude masking effect and the distortion distribution masking effect are fully considered to calculate the virtual viewpoint image The purpose of the distortion mask map is to extract areas with large distortion amplitudes and concentrated distortion distributions, and to effectively distinguish the effects of distortions of different amplitudes and distributions on the subjective quality of the human eye.

Description

technical field

[0001] The invention relates to a technology for evaluating the performance of a virtual viewpoint and a rendering system, in particular to a method for evaluating the quality of a virtual viewpoint based on a visual masking effect. Background technique

[0002] In recent years, stereoscopic video technology has developed rapidly. The Free Viewpoint Video system (FVV, Free ViewpointVideo) is a further development on the basis of 3D video, which can enable users to obtain better visual experience. Depth Image Based Rendering (DIBR) technology is the core of the FVV system, which can overcome the limitation of the camera's ability to obtain real viewpoints and generate enough virtual viewpoints. However, there are many types of distortions in the virtual viewpoint generated by rendering, which will seriously affect the 3D visual experience. Therefore, it is necessary to propose an evaluation scale to measure the quality of the virtual viewpoint. The virtual v...
