Computer aided diagnosis and follow up can help in prevention and treatment of diabetes and its related complications. Screening of diabetes related disease in eye is done by a special low cost fundus camera. A follow up of the patients visiting at different time interval for screening brings us to the problem of image analysis of change detection...

Context 1
... training images of each eye are warped onto the reference co-ordinate system using thin-plate splines [5] shown in figure 10. After all the images are warped into this reference co-ordinate system, we take the mean to get the average color/pigmentation in the population of the same ethnic group. ...
Context 2
... all the images are warped into this reference co-ordinate system, we take the mean to get the average color/pigmentation in the population of the same ethnic group. The mean image is normalized to obtain an atlas map for African American population shown in figure 11. ...
Context 3
... statistical Atlas with all the landmarks is shown in figure 12. A big peak at the optic disk location can be seen and a deep valley at the fovea region. ...
Context 4
... is because other vascular structures, ON and macula will have comparably less distance than the bright lesions. This brings us to an advantage of direct thresholding of these bright structures as shown in figure 13. The direct thresholding of the bright lesion without any pre or post-processing of the image on atlas space can be done with subsequently high detection and segmentation rate. ...
