FASTRMS Instantaneous root-mean-square (RMS) power via convolution.FASTRMS(X), when X is a vector, is the time-varying RMS power of X, computed using a 5-point rectangular window centered at each point in the signal. The output is the same size as X and contains, for each point in X, an estimate...

Contains three matrix completion algorithms and a demo script for running them. Also compares against other matrix completion algorithms - Singular Value Thresholding and Fixed Point Iteration.Solves the following three optimization problems:min rank(X) subject to ||y - M(X)||_2

This function finds dominant peaks and valleys of an image histogram. Minimum peak distance and averaging filter size can be changed to suit your need.Although, the function is originally written for mages, there is no reason why this can't be used on one dimensional data.USAGE:[peaks minima_low...

Maximum Inscribed Circle Or in other words, "largest inner circle" , "maximum empty circle" etc.This is a very common problem in computational geometry, and it is not simple to solve efficiently.Addressing 2D image/contour processing, I couldn't find a good implementation on the web. Generally,...
