Sample code that shows how to extract descriptors from the HPatches dataset using Matlab.
matlab -nodesktop
>> hpatches_extract(hpatches_db_root_folder)where hpatches_db_root_folder points to the folder of the downloaded
HPatches dataset.
After the program ends, you will have folder named misigma
containing the descriptor values for the trivial (μ,σ)
descriptor.
