I have one image in full size and half size. I extract the HOG features from the full size image with a cell size of 8 using extractHOGFeatures and from the hall size image with a cell size of 4 using extractHOGFeatures. I am interested in plotting the difference of the two visualizations. Unfortunately, I am not very familiar with how to do this. Since the features are a in a struct I don't know what and how I am supposed to subtract features to get a difference of features plot. Any help would be greatly appreciated.

The example for extractHOGFeatures shows how to visualize them.
Having said that, the HOG vectors extracted from two images of a different size cannot really be compared.
