Approaches to Shape Modeling and Image Segmentation
Sofia Visa, Assistant Professor of Computer Science, The College of Wooster
Image processing is an active research area with applications in many fields. Sofia Visa will illustrate such an application in Biology by using morphometric (boundary) data of tomato fruits in conjunction with elliptic Fourier shape modeling and Bayesian classification techniques to find the optimum number of shape categories of the tomato fruits. The modeling results show that there are nine distinct shape categories, which are also distinguishable by the human eye. She will also be presenting a new image segmentation framework that combines clustering with edge detection approaches. To demonstrate this framework, she uses the Canny edge detection approach to guide region identification through fuzzy k-means clustering and applies it to several benchmark images.
