WebUpdated Mean Shift Procedure: • Find all modes using the Simple Mean Shift Procedure • Prune modes by perturbing them (find saddle points and plateaus) • Prune nearby – take highest mode in the window. fMean Shift Properties. • Automatic convergence speed – the mean shift vector size depends on the gradient itself. WebMean-shift is a hill climbing algorithm which involves shifting this kernel iteratively to a higher density region until convergence. Every shift is defined by a mean shift vector. The mean shift vector always points toward the direction of the maximum increase in the density. At every iteration the kernel is shifted to the centroid or the mean ...
