Research on Multi-focal Image Fusion Based on Wavelet Transform

Abstract In recent years, wavelet transform theory has been paid more and attention in image fusion. With the development of fusion, is introduced, basic principles types are introduced. Then, aiming at two images with different focal lengths, discrete method three-layer decomposition used, low-frequency high-frequency components fused by fusion rules, differences strategies compared analyzed. Experimental results show that characteristics convenient application, rapid real image, a good application prospect.
