改进的基于图像边缘的能见度反演方法
Improved inversion algorithm based on image edge for visibility
摘要
Abstract
According to the existing method for image edge visibility, the result is not ideal, this paper presents an improved method based on image edge detection for visibility. Firstly, it selects the target image using sift algorithm for template matching, then the discrete shearlet transform is used to extract the edge features, and then these features and the results of forward-scattering visibility meter are related. After establishing the relationship, visibility can be computed by the features with the built relationship. The experimental results show that the relative error is reduced by 2.761% relative to Sobel algorithm, and by 1.607%relative to wavelet transform algorithm. The accuracy and efficiency are obviously improved.关键词
