A Multimodality Medical Image Fusion Algorithm Based on Wavelet Transform

Abstract: Abstract. According to the characteristics of a medical image, this paper presents a multimodality medical image fusion algorithm based on wavelet transform. For the low-frequency coefficients of the medical image, the fusion algorithm adopts the fusion rule of pixel absolute value maximization; for the high-frequency coefficients, the fusion algorithm uses the fusion rule that combines the regional information entropy contrast degree selection with the weighted averaging method. Then the fusion algorithm obta… Show more

“…Similar to neural network, the kernel based operators such as support vector machines (SVM) can be used along with wavelets to achieve image fusion at feature levels [66]. Considering wavelets as a fusion operator, several feature processing methods can be combined such as wavelet-SVM [66], wavelet-texture measure [29], wavelet-MRA [30,67], wavelet-self adaptive operator [69], wavelet-resolution-entropy [70,72], nonlinear wavelet-shift invariant imaging [71], ICA-wavelet [86], wavelet-edge feature [75], waveletgenetic [59], wavelet-contourlet transform [81], neuro-fuzzy-wavelet [82] and wavelet-entropy [84].…”

“…The primary concept used by the wavelet based image fusion [26][27], [59,[61][62][63][64][65][66][67][68][69], [40], [70][71][72][73][74][75][76][77][78][79][80][81][82][83][84], [29,30,[32][33][34] is to extract the detail information from one image and inject it into another. The detail information in images is usually in the high frequency and wavelets would have the ability to select the frequencies in both space and time.…”
