直方图重建图像细节增强算法
Novel histogram reconstruction based image detail enhancement algorithm
摘要
Abstract
To solve the problem that the 8 bit quantization results of the traditional high dynamic range image compres-sion methods are easily influenced by image background change, quantization images blur, image detail and dim target loss, a novel histogram reconstruction based image detail enhancement algorithm is proposed. Firstly, image histogram statistics is reassigned to save image details and reduce the interval of adjacent gray level. Secondly, Gabor filters are used to simulate visual perception system, and smooth images are acquired by using Gabor filters. Finally, local contrast enhancement method is used to enhance image details, and linear mapping 14 bit enhanced image to 8 bit display image. The experimental results demonstrated that the quantization images of the proposed algorithm are more distinct and have more image details comparing with traditional quantization methods.关键词
