This is the Difference of Gaussians

In the realm of image based edge detection, aesthetically pleasing edges are hard to come by. But, what if we could get stylized edge lines by just blurring our image twice? Download my GShade shader pack! https://github.com/GarrettGunnell/AcerolaFX/wiki Patreon: https://www.patreon.com/

Mixture Models 4: multivariate Gaussians

Full lecture: http://bit.ly/EM-alg We generalise the equations for the case of a multivariate Gaussians. The main difference from the previous video (part 2) is that instead of a scalar variance we now estimate a covariance matrix, using the same posteriors as before.
