So, lets get down to it. Focusing on sparse Laplacian matrices consisting of a data term and a prior term (typically defined using four or eight neighbors for 2D image), our approach efficiently solves such global objective functions. For unsigned integer arrays, the results will also be unsigned. This example shows how to blur an image using Gaussian smoothing filters of different strengths. Local linear regression can be applied to any-dimensional space, though the question of what is a local neighborhood becomes more complicated. Estimate the frequency response for a Gaussian filter by Gaussian smoothing an image, and taking its Fourier transform both before and afterwards. The simplest smoothing algorithm is the "rectangular" or "unweighted sliding-average smooth". However, the more accurate estimate is of the mean of a local pixel neighborhood! This might not be what you want. This toolbox supports inference and learning for HMMs with discrete outputs (dhmm's), Gaussian outputs (ghmm's), or mixtures of Gaussians output (mhmm's).
