摘要

This paper puts forward a remote sensing digital image enhancement based on lossless panning bidirectional stretching. The effective pixel in remote sensing digital image will be panning to 128 according to its brightness mean and then perform lossless bidirectional contrast stretching on remote sensing image. Then, the image is taken as data foundation after it is enhanced by lossless false color composite. The data foundation is improved during principal component analysis and the principal component analysis is used for removal treatment on abnormal interference factors. Finally, the second main component image with effective removal of abnormal interference factor will be selected. Discrete wavelet transform is used for edge detection and abnormal region delineation according to edge detection and geoscience in experiment region to obtain more accurate geological detection forecast map.
