Forgiveness and Failure of the Heart
… of cardiovascular disease can be measured by an angiogram. This procedure measures the degree of occlusion in major arteries of the heart. This physical measurement was correlated with patient's tendency to be forgiving of themselves and others. This measurement reflects forgiveness as a …

A novel automated approach of multi-modality retinal image registration and fusion
… images are from two different modalities, i.e. angiogram grayscale images and fundus color images. The relative study of retinal images enhances the information on the fundus image by superimposing information contained in the angiogram image. Through the thesis research, two new contributions …
