Just-Noticeable Distortion Estimation for Image Pixels
This paper addresses the issue of incorporating contrast sensitivity function (CSF) into just-noticeable distortion (JND) estimation for image pixels in spatial domain. Based upon our earlier work on DCT-subband JND estimation, the resultant new pixel-wise JND model fully incorporates the spatial CSF, in addition to considerations of luminance adaptation and local contrast masking effect. Various experiments confirm the improved accuracy of the proposed model over the existing relevant JND estimators
