MEDICAL IMAGE FUSION ALGORITHM USING TREE-STRUCTURE WAVELET TRANSFORM AND ITS IMPLEMENTATION
摘要
Abstract
An algorithm for medical image fusion based on tree-structure wavelet transform is proposed. Following some special energy criterion, it can implement adaptive tree-structure wavelet decomposition on image and can determine image transform according to the sub-image energy of the image. The algorithm is simulated through experiment and assessed based on objective image fusion criteria. Experimental results show that the tree-structure wavelet decomposition can achieve better fusion outcome than that of the pyramid wavelet decomposition, the signal-to-noise ratio has improved a lot, and the mean-square deviation reduces significantly. The proposed algorithm not only retains the multi-resolution characteristics of the wavelet, but also fully retains the details in the image, and reduces the complexity of fusion.关键词
