Abstract

The invention discloses a multisource and multi-focus color image fusion method and relates to a computation method of multisource and multi-focus color image fusion. The multisource and multi-focus color image fusion method solves the problems of color distortion and a blurring effect in the available multisource and multi-focus color image fusion technology. The fusion method comprises the steps of modeling a plurality of original color images to be fused in a two-dimensional exchangeable Clifford algebra manner, achieving the integrated processing of the color images, conducting Clifford shearlet transformation on the color images after the integrated processing respectively, obtaining thick scale coefficients and thin scale coefficients of the color images, selecting the coefficient with a minimal norm value as the thick scale coefficient of fused color image, selecting the coefficient with a maximal norm value as the thin scale coefficient of the fused color image, conducting inverse Clifford shearlet transformation, and obtaining the fused color image. The fusion method can remove the image blurring farthest.

Description

technical field [0001] The invention relates to a calculation method for multi-source multi-focus color image fusion, in particular to a color image transformation domain calculation method for multi-sensor image fusion. Background technique [0002] Image fusion has important applications in medicine, remote sensing, and military target recognition. In practical applications, it is necessary to fuse images obtained by multiple sensors to achieve information complementarity between different images, to enhance the transparency of information in the image, to describe the target clearly, completely and accurately, and to facilitate subsequent decision-making. Provide reliable information support. [0003] In order to ensure the quality of multi-source color image fusion, it is required to have a high degree of color reproduction and a small degree of image blur in the process of image fusion calculation. In the calculation process of image fusion, the method of space domain...
