Abstract
In recently, it is needs a new transform coding method to generate super-high-quality images in super-high-resolution display environment. I focus on the mosquito noise appeared by AC quantization error in AC frequencies for DCT and propose its quantification and noise evaluation. From the results, it has to set to quantization errors less than 13, 9, and 7 contrast to the edge nodes 2, 3, and 4, respectively. It was clear that WDCT to arrest divergence of AC frequencies by improving within frequency resolution is realizable to 19.59% mosquito noise of DCT.
