Abstract: The aim of this paper is to construct an image recongnition system based on Gabor wavelets for infrared image. An enhanced representation of the Gabor wavelets is proposed, in which the properties of Gaussian mask in Gabor wavelets is developed to enhance the envelope function, and simultaneously the parameters of the filter based on Gabor wavelets is designed depengding on the frequency response of the training images. Some experiments including infrared image recognitions are given. The good performances are verified through using the proposed scheme in this paper.
