PPT-An efficient image segmentation algorithm using bidirectional

Mahalanobis distance MASTERS THESIS By Rahul Suresh COMMITTEE MEMBERS DrStan Birchfield DrAdam Hoover DrBrian Dean Introduction Related work Background theory Image as a graph. Why deal with sequential data?. Because all data is sequential . . All data items arrive in the data store in some order. Examples. transaction data. documents and words. In some (or many) cases the order does not matter. Varun. . Gulshan. †. , . Carsten. Rother. ‡. , Antonio . Criminisi. ‡. , Andrew Blake. ‡. and Andrew . Zisserman. †. . 1. Star-convexity. †.
