Color Bleeding Reduction in Image and Video Compression

摘要：

Color bleeding is an annoying chromatic color artifact in DCT-coded technology. We propose an efficient postprocessing technique in YCbCr color space, which is commonly used in image and video compression, based on adaptive filtering specifically to reduce color bleeding artifacts while preserving the edge sharpness of the reconstructed images. Simulation results show that the method effectively improves image quality both objectively and subjectively. The PSNR in chroma channels gains a lot and the visual quality is improved effectively.
