Contrast-Based Image Fusion in Wavelet Domain

Wavelet direction contrast based on wavelet multi-resolution and HVS is applied into image fusion. A new fusion scheme is proposed, in which a correlated salience measure function and a normalized correlation measure function for source images are defined while a simple equation for weighed fusion coefficients selection is adopted. Experimental results demonstrate that this improved scheme not only has a better visual effect than former fusion schemes, but also simplifies the computation complexity
