The paper presents a new technique of efficient dynamic range compression and shadow compensation for still color images. The proposed method enhances low light areas while preserving the colors and details, without generating visual artifacts. The approach is based on recursive filtering and contrast stretching techniques, driven by statistical measures of the image and implemented under a logarithmic image processing model. The implementation can be used for any image represented in the RGB or YCbCr color spaces.
