The Visioneers

Few hour ago, I was reading some papers to increase my understanding on support vector machine (SVM).  I came across the term convex hull and I was reminded of challenge I had when I was working on image segmentation of medium to long milled rice grains for quality evaluation. Although there are some published papers that deal with this problem (e.g. “automatic segmentation of touching kernels with gradient vector flow” and “Separation and identification of touching kernels and dockage components in digital images“), they were able to solve only those touching grains with circular-like objects.

So I thought, using convex hull to define the initial boundary of an active contour could be an interesting idea.  But it looks like somebody has already done it – see An unsupervised GVF snake approach for white blood cell segmentation based on nucleus.
