Improved DCT-domain Color Image Enhancement through Anisotropic Diffusion
首发时间:2009-12-28
Abstract:Color image enhancement directly in the DCT domain is an efficient approach in high speed data transmission. However, such methods often suffer from blocking artifact due to inappropriate scaling between adjacent blocks. We propose an improved method based on anisotropic diffusion that overcomes this difficulty. Simulation results show that the proposed method can effectively remove blocking artifact introduced during the DCT coefficient scaling stage, resulting in much improved performance over some of state of the art methods.
