The Research Of Application Of Ridgelet Transform In The Fusion Of Multispectral And Panchromatic Images

Image fusion is a branch of the information fusion. Image fusion's research field is the fusion methods of images come from different sensors or images from the same sensor at different moment. Through taking advantage of the complementary information and the redundant information, the output image of image fusion can provide more comprehensive and more accurate description about the scene. The technique of the image fusion has been applied in the fields of military matter, remote sensing, robot, the processing of medical image and machine vision.This paper describes the theory of the Ridgelet transform and provides a way of the implementation of the Ridgelet transform. At first, through the radon transform on the 2-d Fourier domain, we get radon domain, second, using 1-d wavelet transform on every direction on the radon domain, we get the Ridgelet coefficients.In this paper, through using Slant Stack and bilinear interpolation, we get the result of the Ridgelet transform. After this work, we put the way of implementation of the Ridgelet transform in the fusion of Multispectral and Panchromatic Images. The experiment show the performance of the Ridgelet transform in representing the high-dimension singularity is better than wavelet transform.
