Improved algorithm for removing horizontal stripe noise in linear array image based on line tracking

The invention provides a method for detecting a stripe position based on a horizontal stripe noise image. According to a sudden change caused by a horizontal stripe noise in a linear array image, thepositions of feature points in the image are determined by utilizing a line tracking method; and through a relationship among the feature points, position information of the horizontal stripe noise isdetermined. In the position of the horizontal stripe noise, the horizontal stripe noise is processed by using a Lagrange interpolation method through utilizing radiation value inheritance of surrounding information, so that quick removal of noise interference in the position of the horizontal stripe noise is realized. A remote sensing image, with the horizontal stripe noise, of a high-resolution1 satellite is processed; and a result shows that an algorithm can effectively and quickly remove the horizontal stripe noise in the image by utilizing features of the horizontal stripe noise, so thatthe image quality is improv
