Embodiment Construction
[0086] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0087] Since multi-viewpoint video signals are finally perceived by human eyes, in order to effectively save depth video coding bit rate on the premise of maintaining the visual perception quality of virtual viewpoints, the present invention proposes a depth detection method based on a fovea just perceivable distortion model. A video coding method, which uses the relationship between depth video distortion and rendering viewpoint geometric distortion, based on the existing Foveated Just Noticeable Distortion (FJND) model, from the perspective of virtual viewpoint rendering quality. MVD encoding to reduce the encoding bit rate of depth video.
[0088] A kind of depth video coding method based on the fovea just perceivable distortion model of the present invention, it comprises the following steps:
[0089] ① Denote the left view video of the d...
