Construction of computational procedure of local image processing on the base of hierarchical regression intended to solve the satellite images processing tasks
Image Processing Systems Institute of RAS
The article is devoted to the use of an algorithm of automatic construction of computational procedure of local nonlinear processing of digital signals/images for satellite images processing. The computational procedure is based on local discrete wavelet transformation of the image used for the preliminary analysis of the image, and hierarchical regression used to obtain the transformation result. The construction procedure is based on training information (pair of images «original» – «the result of processing»), takes into account the restriction on the complexity of the constructed transformation and maximize the processing quality and generalization ability. The paper presents examples of using of the proposed image processing procedure for solving different tasks of satellite images processing.
