A Study of PCA Image Fusion Techniques on Remote Sensing

摘要

We propose a PCA algorithm for image fusion between the infrared image and the visible image of the same night vision. The infrared image and the visible image are preprocessed with image Gaussian low-pass filter respectively, to smooth the images. The mathematical formulation of image fusion techniques is worked out in this paper. Included are block-based method, wavelet transform, wavelet packet and PCA. Experimental results show the effectiveness of the proposed method.
