摘要：Medical image fusion will help the physicians to extract the features visible in images by differentmodalities. In this paper, a novel discrete wavelet transform (DWT) based technique for medical image fusion ispresented. Firstly, the medical images to be fused are extracted .Secondly conversion into grayscale is carried outbefore decomposition by the DWT. Then by considering the characteristics of human visual system (HVS) and thephysical meaning of the wavelet coefficients, new different fusion schemes are performed on low frequency and highfrequency bands separately, i.e. Visibility Based Scheme for the low frequency coefficients and Variance BasedScheme for the high frequency coefficients are applied. Finally, the fused image is constructed by the inverse discretewavelet transform (IDWT) with all the combined coefficients.
