Web29 aug. 2010 · HVS is so complex that it is impossible to incorporate the whole HVS characteristics during rate control and video coding. This paper only discusses several … WebThe proposed method can classify the images according to the features of their multiple PEHs and adaptively conduct the data embedding according to the HVS model. Taking the HVS-based quality metric into consideration, we propose a new optimization objective based on the MHM framework, in which the quality distortion is evaluated by the NVF.
