Visual agnosia (a nerological disease) is the inability of the brain to make sense of normal visual stinulus.It is often due to damage in posterior occipital in the brain. The SPECT image indicates the disease function and has a low spatial resolution so the dimensions of the disease are not clear. in this paper , using new advanced retina based fusion model . the spatial characteristecs that extracted from MRI image is injected to the SPECT image the proposed algorithm combines the advantages of both IHS (Intensity - hue - saturatuin) and retina - inspired model fusion methods to improve the functional and spatial information content . the results show that the fused image is more informative for clinical application.
