From: Rigid Registration of Renal Perfusion Images Using a Neurobiology-Based Visual Saliency Model
Saliency maps of contrast enhanced image sequence. (a)–(d) show images from different stages of contrast enhancement with added noise. The variance of noise added was .02, .05, .08, and .1. (a) is the reference image to which all images are registered. (e)–(h) show the respective saliency maps; (i) colorbar for the saliency maps. The saliency maps are seen to be similar. Color images are for illustration purposes. In actual experiments gray scale images were used.
