基于Retinex和BM3D的图像增强
Image enhancement based on Retinex and BM3D
摘要
Abstract
In order to overcome the noise problem of traditional Retinex algorithms, we propose an image enhancement algorithm based on Retinex theory and Blocking Matching 3D (BM3D). This new algorithm adds the denoising links of BM3D into the traditional Retinex algorithm. First, it calculates the relationship of relative lightness between each pixel and corrects the value of each pixel of the image to be handled. Then, through searching similar block among the adjacent tiles, it forms a three-dimensional matrix and filters in 3-D space and gets a preliminarily estimated value. At last, it gets the final result by the weight of each pixel. The experimental results show that the proposed method not only displays the details of the shadow area and lighting areas, but also eliminates the noise contained in the image, overcoming the drawback of traditional enhancement algorithms of Retinex.关键词
