In matlab 2014b in vision toolbox, in extractHOGFeatures.m there's a line that says
hog = visionExtractHOGFeatures(gMag, gDir, gaussianWeights, params, weights);
I've looked for visionExtractHOGFeatures everywhere in matlab it seems to be a function, but I can't find anything about it. extractHOGFeatures.m uses it, it seems to be important for the algorithm and I want to fully understand the code. What can it be? How can I find what it is?
It is an internal function. Unfortunately, you cannot see the source, because it is compiled code.
