Removal of random stripe noises in remote sensing image by directional filter

Stripe noise is one of the most important factors which influence the qualities of remote sensing digital images. A new destriping method based on 2-D directional filtering was proposed based on the analysis of the main causes and characteristics of the stripe noises in remote sensing images. The directional filter can isolate the directional information of the stripe noise from the noised image, so it is easy to uniform the gray value of the image along column by mean equalization. The results prove that this method can effectively remove the stripe noise while keep the detailed information of the original image.
