Multi-view video coding system utilizing visual characteristics

The invention relates to the technical field of joint multi-view video coding, in particular to a multi-view video coding system utilizing visual characteristics. The system comprises a just noticeable distortion threshold value computing module of a discrete cosine transform (DCT) domain and a multi-view video coding module, wherein the just noticeable distortion threshold value computing module of the DCT domain comprises a space contrast sensitivity function sub-module, a background brightness masking effect sub-module, a texture masking effect sub-module and a time contrast sensitivity function sub-module; and the multi-view video coding module comprises a predictive coding sub-module, a DCT coding sub-module, a DCT domain filtering sub-module, a quantification and entropy coding sub-module, a video sequence reconstruction sub-module and a rate distortion optimization sub-module. By the system, a just noticeable distortion (JND) module of the DCT domain is established, and is applied to the DCT domain filtering sub-module and the rate distortion optimization sub-module in multi-view video coding, so that a multi-view video coding rate can be decreased and multi-view video coding efficiency can be improved under the condition of unchanging subjective quality.
