Abstract
This monograph has described the JND threshold for DCT-II subband, which is formulated as a product of the detection threshold and the elevation parameters, namely, luminance adaptation and contrast masking. Based on this formulation, we review Chou’s [CL95], Yang’s [YLL05], Watson’s [Wat93], Wei’s [WN09], and Zhang’s [ZLX05] JND models. We have also shown how these JND models can be integrated into DCT-II based PICs, which are compatible with the JPEG standard. Although there has been significant development in the computational models for JND, a number of challenges still remain in this field.
