摘要

The image enhancement and implementation of the methods for the digital image enhancement werestudied. The characteristics of different image enhancement methods, including contrast enhance-ment, linear transformation, piecewise linear transformation, grayscale slice transformation and Retinexclearing algorithms were analyzed in detail. Retinex enhancement algorithms were studied and theimplementation process for the Retinex algorithm is given. Finally, an example of image enhancementusing the multi scale Retinex algorithm (MSR) is achieved. It is shown that MSR can realize the imagecolor constancy, local dynamic range compression, color enhancement and the overall dynamic rangecompression under certain circumstances.
