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?

Requires the wavelet toolbox to run (uses the wfusmat function)

23 Jan 2014 Law's Texture Filter Implementation of Law's texture filter from 1980, input is an image and output 6 filtered maps. Author: Lukas Tencer Faraz

Undefined function 'wfusmat' for input arguments of type 'double'.

Error in laws (line 41)
mapz{end+1}=wfusmat(filtered2D{2},filtered2D{5},'mean');

Hello, i am new in matlab and i have a question for the above code.Can you please tell me how to show the images that you have avatar with this code?

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.
