Interactive Color Image Segmentation Editor Driven by Active Contour Model

A new general-purpose color image segmentation editor (CISE) for the purpose of extracting a semantic object is designed, implemented and tested on a number of various natural scene images. Our editor integrates a deformable model and image statistics including intensity, color, gradient and texture. The editor starts with a coarse region segmentation which applies the Canny’s operator followed by a lowcomplexity edge linking algorithm. This segmentation basically builds regions of smooth intensity by closing all dangling edges. Next, a topologically-based region labeling method makes full use of relationship among pixels and produces useful labeled image. Finally, to refine the extracted object of interest (021), a deformable model based on energy minimization is applied by incorporating both the gradient and region . criteria to the external constraint force. These processes are demonstrated through examples on natural scene color images. Experimental results suggest the eficiency and accuracy of the algorithm in its segmentation operations.
