%X Because of failing to reconstruct piecewise constant illumination, variation Retinex method suffers from artificial halos and color distortion. A Retinex method based on robust estimation was proposed, which took shadow edges as outliers and smoothed range by range. Application of method to synthetic image and natural image proves that the improved method preserves high dynamic range compression and avoids halo effect and color distortion.
