摘要
提出了一种基于Retinex理论的图像增强算法。Retinex理论的实质就是从图像S中抛开照射光L的影响来获得物体的反射性质R,即获得物体本来的面貌。在对Retinex理论进行研究的基础上,论述了该算法的原理和实现方法,并通过实验与几种传统的图像增强方法以及单尺度、多尺度和带彩色恢复的多尺度Retinex进行了比较,表明该算法对于图像阴影细节的增强和色彩的保真较一般的图像增强算法能够达到更好的效果。
An algorithm for image enhancement based on the Retinex theory is proposed. The essence of Retinex theory is to abandon the illumination in the original image and to yield the reflectance image, that is, the original appearance of the object. The theory and realization of the algorithm are presented. A comparison of other conventional image enhancement algorithms and single - scale Retinex, Multi - scale Retinex and Multi - scale Retinex with color restoration shows that it has better performance in enhancing the shadow details and maintaining the original color.
