We investigated Generalized Gradient Vector Flow Active Contours as a suitable boundary mapping technique for Chromosome spread images which have variability in shape and size, expecting to yield a robust segmentation scheme that can be used for segmentation of similar class of images based on optimal...

In previous impedance metasurface theories, it is often required that the two boundaries have the same shape \({\Gamma }^{0}(x,y,z)\) and normal vector \({{{\bf{n}}}^{0}(x,y,z)\), i.e., that they are parallel. Continuity of normal power flow is then imposed strictly24....

In particular, we propose the truncated Rayleigh flow method (Rifle) to estimate the leading generalized eigenvector and show that it converges linearly to a solution with the optimal statistical rate of convergence. Our theory involves two key ingredients: (i) a new analysis of the gradient ...
