24 Jan 2013 HOG descriptor for Matlab Image descriptor based on Histogram of Oriented Gradients for gray-level images Author: Oswaldo Ludwig

Also you are doing normalization of the final vector, originally it supposed to be blockwise normalization, did you try that version? Why you decided for normalization only of final histogram.

Should not be contribution of individual points to the histogram weighted according to gaussian centred in the middle of each cell?

Documentation is a bit lacking, maybe worth adding input checking too. But I can see myself using it, thanks.

May help noting that borderpolicy may be a scalar or string ('circular', 'replicate', 'symmetric') and only applies if the subwindow is outside the original image space.
