多源遥感图像融合的数据同化算法
Data Assimilation Algorithm of Multi-fountain Remote Sensing Image Fusion
摘要
Abstract
To solve the problem that the fusion rules could not be adjusted serf-adaptively with the available fusion methods according to the following processing requirements of remote sensing (RS) image, this paper builds a data assimilation system by integrating the merit of model operator and observation operator, and presents an RS image fusion scheme based on data assimilation and genetic particle swarm algorithm. The arithmetic takes the plain-move invariant wavelet transform as a model operator, and takes the contrast pyramid as observation operator. Also the scheme ascertains the weights of the attribute indices according to their dependent degrees to attribute indices of image by following processing. And then the algorithm designs the objective function by using the weighted sum of evaluation indices. Moreover, the arithmetic optimizes the objective function by employing genetic particle swarm algorithm to obtain a higher definition RS image. This paper proves the superiority of the proposed scheme by syncretizing RS panchromatic image and multi-spectral image as well as inosculating infrared image and visible light image.关键词
