Therefore, we propose the MOORGB which uses multiobjective optimization method (maximizing the difference between target and background, improving the uniformity within the target region, considering the edge gradient) to improve the segmentation performance.
For each pixel the local edge gradient magnitude is estimated with the maximum response of all 8 kernels at this pixel location.
The edge gradient features are commonly extracted by a series of differential operators based on derivative information.
The method representing the shape via edge gradient direction is more operable and feasible, as it requires less prior-period image processing works.
