Block DCT based image fusion techniques have been developed and studied
using image fusion quality evaluation metrics. Five image fusion architectures
such as feature (FDCT), resizing DCT (RDCT), wavelet structure DCT
(WSDCT), subband DCT (SDCT) and Morphological DCT (MpDCT) based on
block DCT have been demonstrated. It is observed that WSDCT based image
fusion algorithm out performed. The Matlab code will be distributed.
