Because of the difference response among the detectors in the pushbroom satellite, striping is an obvious phenomenon in the remote sensing image along the scanning direction. A relative radiometric correction algorithm is put forward based on the adaptive filtering pattern. Firstly, the suitable 1-D nonlinear filter is chosen to remove the obvious striping according to the image striping distribution. Then, the 1-D smoothing filter is used to calculate the gain and offset coefficients. At last, the thin stripping is destriped with the obtained coefficients. The comparison experiment proves that the algorithm can effectively improve the image quality, and remove the stripping along the scanning direction, at the same time it preserves the image detail.
