setting up hog pyra ... segfault inside malloc in fhog. this didn't happen before i started doing downsampling
hmm, if i go up to i=5, i get a segfault. but, to i=2, no segfault.
aha, the problem happens for i=4
i think the problem might not actually be in the malloc/free statement; it's just that the error gets caught here
aha, there seems to be a problem with mxFree(R1). might actually be the problem.
aha, the problem is almost certainly a discrepency on how my code vs. piotr's code calculates hogHeight and hogWidth
it runs now -- fiddled with hogWidth and hogHeight. (need to standardize this more through my code and piotr's code)
it's pretty slow now ... i bet the transpose aint cheap
removed timers -- will put them back after i refactor
