An enhanced snakes algorithm (ESA) for detecting object contours is designed and developed. In the ESA, a novel split and merge technique is added to the original snakes model to enhance the model to support the detection of concave object contours. A set of handtools is selected to evaluate the proposed algorithm, and the results are encouraging.
