Problems solved by technology
Filtering-based methods mainly include wavelet analysis, Fourier domain filters, and combined filters, which show superior performance in removing periodic bands, but are prone to blurring or ringing effects
Statistics-based methods mainly include moment matching and histogram matching and their improved methods. The results of this type of method largely depend on the pre-established reference moment or histogram; however, it is difficult to find a suitable Reference moment or histogram, poor practicability
Optimization-based methods usually introduce the prior knowledge of strips and clean images into the energy function, and usually achieve good results, but when the density of strips is high, especially in the experimental results of non-periodic strips, it is easy block effect

The invention relates to the technical field of remote sensing image processing, and provides a strip noise fusion correction method and device, electronic equipment and a storage medium. Performing primary correction on each pixel of the remote sensing image by using a radiation response uniformity correction method to obtain a first corrected image; and performing secondary correction on each pixel of the first corrected image based on an image processing method to obtain a second corrected image in which the stripe noise is completely eliminated. By combining radiation response uniformity correction and noise correction based on image processing, stripe noise is effectively eliminated, and meanwhile, the problems of image blurring, ringing response, block effect and the like caused by a complex algorithm are avoided, so that the quality of a remote sensing image is improved, and the performance of the remote sensing image is improved.
Description
technical field [0001] The present application relates to the technical field of remote sensing image processing, and in particular, to a method, device, electronic device and storage medium for fusion correction of stripe noise. Background technique [0002] With the rapid development of remote sensing technology, space remote sensing images are widely used in military reconnaissance, disaster monitoring, weather forecasting and other fields. Affected by the non-uniformity of the sensor radiation response, the distortion of the optomechanical system itself, and the changes of the external environment, remote sensing images are easily disturbed by stripe noise. Banding noise will cover the spatial distribution characteristics of the target and generate corresponding pseudo-structures, which not only affects the quality of the image, but also affects the subsequent inversion analysis and information extraction, and ultimately reduces the performance of remote sensing images. ...
