An image segmentation scheme that utilizes image-based flow fields in a curve evolution framework is presented. Geometric curve evolution methods require an edge function and a vector field with certain characteristics that are obtained from the image itself. A vector field borrowed from the edgeflow segmentation (Ma and Manjunath 2000) method is utilized both to obtain an edge function and to guide the curve evolution towards the object boundaries. This vector field is computed from the image using intensity, texture and color features. The proposed method integrates well-tested image features with the well-studied curve evolution methods thus achieving better segmentation results.
