Selective Segmentation for images with weak edges -- Segment a given 2D image (CoV with prior knowledge: AOS solver) --- (2012)

Software for Selecting an Object with weak edges in a large image

``Coefficient of Variation Based Image Selective Segmentation Model Using Active Contours'', N Badshah, K Chen, H Ali and G Murtaza (2012)
East Asian Journal on Applied Mathematics , Vol. 2 (2), pp. 150-169, 2012. See PDF file.
See the left image for an example of selection by 2 vertices / markers and the segmented result below.
(Note: as with CV2, this model is not convex so the result might be sensitive to initial contours and also the input parameter α]. But more markers do help.
