Journal ArticleDOI
Multimodal Medical Image Sensor Fusion Framework Using Cascade of Wavelet and Contourlet Transform Domains
TL;DR: A two-stage multimodal fusion framework using the cascaded combination of stationary wavelet transform (SWT) and non sub-sampled Contourlet Transform (NSCT) domains for images acquired using two distinct medical imaging sensor modalities is presented.
Proceedings ArticleDOI
Medical image fusion with Laplacian Pyramids
TL;DR: The proposed technique provides a fused image with better edges and information content from human visual system (HVS) point of view and is found to be superior than that of Daubechies complex wavelet transform (DCxWT).
Proceedings ArticleDOI
Medical image fusion using combination of PCA and wavelet analysis
TL;DR: Medical image fusion for merging of complementary diagnostic content has been carried out using Principal Component Analysis (PCA) and Wavelets and results demonstrate an improvement in visual quality of the fused image in comparison to other state-of-art fusion approaches.
Book ChapterDOI
Medical Image Fusion in Curvelet Domain Employing PCA and Maximum Selection Rule
TL;DR: The proposed fusion approach involves image decomposition using curvelet transform followed by application of PCA for dimensionality reduction and the selection of maximum matrix to select only the relevant information in the images.
Journal ArticleDOI
Medical Image Fusion in Wavelet and Ridgelet Domains: A Comparative Evaluation
TL;DR: The outcome of this analysis highlights the trade-off between the retrieval of information content and the morphological details in finally fused image in wavelet and ridgelet domains.
