| contents | A non parametric, level set free method is proposed for detecting image boundaries using the shape gradient of the Mumford Shah energy for segmentation. Minimizing the variance in pixel intensities inside and outside a boundary set of points is the primary pursuit. The boundary set as a polygon of points rather than a parametric form or a level set, evolves under the guidance of a shape gradient of the Mumford Shah piece wise constant segments model. Iteratively updating through the gradient descent method. The proposed method has been tested on various images, demonstrating its effectiveness in capturing intricate and narrow boundaries texture images. |
