Hi,
I am implementing HOG myself (not using extractHOGFeatures) for my coursework. I could able to implement HOG completely by referring Dalal paper. The hardest part is visualisation of the extracted features. Actually visualisation is tougher than creation of HOG iteself!
I tried http://www.vlfeat.org/overview/hog.html, but it seems the implementation of HOG is little different from MATLAB.
Does any one know how to visualise HOG once it is manually extracted? It will be a great help.
Thanks in advance!
Regards, Aravind

Thanks. But I am implementing manually. I don't want to use built-in extractHogFeatures I have already implemented HOG but I needed some routine which can give visualization
