Detection and removal of the stripes in MODIS 1B image
MODIS 1B 影像条带检测与去除

The MODIS sensor has 36 spectral bands. the desired effect can not be obtained with only one destriping method. Based on compensation and elimination of equalization curve method, a new set of algorithm is proposed in this article to rapidly detect and remove stripes, through giving a definite judging parameter of the stripe. If the correcting coefficient of 10 groups sensors in A-frame and B-frame are separated by 0, and the ABS (Ci)>0.008, then there exist wide stripes. If the maximum correcting coefficient (C?i) of 10 groups sensors is greater than 0.05, then there exist single-line stripes. The wide destriping process is as follows. Take the current column as the first one; then extract the correcting coefficient from the next 100 columns of each sensor compared with the first column seperatively. The results show that the detecting model can effectively identify the single-line stripes and the wide stripes, but the multi-line stripes need visual assistant. The removal effect of the single-line and the wide stripes is better than that from NASA website, the image quality is significantly improved after the treatment, though multi-line stripes are not completely removed.
