Image data compression using new halftoning operators and run length encoding
A new approach for removing blocking artifacts in reconstructed block-encoded images is presented in .The perceptual quality of video affected by packet losses, low resolution and low bit video coded by the H.264/AVC encoder is studied in . Digital halftoning is a nonlinear system that quantizes a gray level image to one bit per pixel. Halftoning by error diffusion scans the image, quantizes the current pixel, and subtracts the quantization error from neighboring pixels in fixed proportions according to the error filter. The error filter is designed to minimize a local weighted error introduced by quantization.
