  A scheme for multi scale based feature level image fusion for Multimodal medical images has been proposed here. The scheme is based on joint cascaded framework of Lifting wavelet transform (LWT) with Non subsampled contourlet transform (NSCT). These multiscale decomposition (MSD) methods are used back to back to decompose the images of different medical modalities. The low and high frequency coefficients obtained from two stage decompositions are fused according to different fusion rules. At first stage high frequency components (detail information) are fused by Karhunen –Loeve (KL) transform while low frequency by weighted superposition. Later on at second stage the max rule fusion method has been employed for both. Image reconstruction at the intermediary level is obtained by applying Inverse LWT (ILWT) and at final stage Inverse NSCT has been employed. Haar wavelet function i.. Read More»
