A New Method of Relative Radioactive Correction Based on Image Statistic
一种基于图像统计量的相对辐射纠正算法

Vertical striping is an obvious phenomenon in pushbroom CCD image because of the different response among CCD detectors and the odd/even effect raised in signal transferring. Image relative radioactive correction is a process to reduce or eliminate these factors and resume the true radioactive information. In this paper, a new method is brought forward aiming to destripping the strips in broad swath CCD image. The method is based on the column average and standard deviation of raw image. Compared with classical methods based on image statistic, this method obtains relative radioactive calibration coefficients independent of uniform image, which is validated in the relative radioactive correction for raw image of Beijing-1 microsatellite.
