The Application of IaCLA Model to Adaptive Image Quantization
Yuan Ying Jiang, Wu Lu, Tao Huang · Advanced materials research · 2012
The quantization scheme proposed in this paper uses a nonlinear transform to exploit the visual masking such as brightness masking and contrast masking, etc. It’s based on the IaCLA model derived from the intra-band masking. The application of the proposed strategy to JPEG2000 coding framework is presented, and the experimental results show the proposed approach can efficiently protect low amplitude wavelet coefficient and discriminate the simple edge even in the smooth region.
