A Line Enhancement Algorithm for Infrared Image Based on Ridgelet

Article Preview

Abstract:

In order to well detect target’s line character for infrared image, we propose improving line character in image through using ridgelet transform which is a kind of multiscale geometric analysis tool and it is especially suitable for describing the 2-D signals which have linear or super-plane singularities. This paper briefs the principle of ridgelet transform and explains our enhancement algorithm in some detail. Its core consists of the method of tensile scale of coefficient in Radon transform domain, filtering method in processing of one dimensional wavelet transform and the algorithm steps of improving line character. It reconstructs images and compares with the other traditional method as presented and analyzes scale of coefficient and time complexity. Our enhancement method is proved effective preliminarily by experimental results.
