A Local Image Enhancement Method Based on Adjacent Pixel Gray Order-preserving Principle[C]. 5th International Symposium on Photoelectronic Detection and Imaging (ISPDI) - Infrared Imaging and Applications. Beijing. June 25-27, 2013.A Local Image Enhancement Method Based on Adjacent Pixel Gray Order-preserving Principle.
مصطلحات موضوعية: The paper is committed in local image enhancement. At first, the authors propose an adjacent pixel gray order-preserving principle. Adjacent pixel gray order-preserving principle is the basement of local enhancement method which ensures that there is no distortion in processed image. And then, the authors propose an iterative algorithm, which could stretch gray-scale difference of adjacent pixels in premise of not changing gray magnitude relationship between adjacent pixels. At last, the authors propose a totally reference image quality assessment method based on adjacent pixel gray order-preserving principle. According to this quality assessment method, the authors made a set of comparative experiments with local histogram equalization and method. Experimental results show that the proposed enhancement method can get higher score and provide better visual effects, fully demonstrating its effectiveness. According to this quality assessment method, the proposed method shows a good effectiveness, through experimental results and comparison with local histogram equalization method
