cool demo!
-
i have built opencv 2.2 with cuda and NPP support with visual studio 2008. I also installed the latest version of the cuda dev nvidia driver and the cuda sdk and toolkit. however, when i try to run hog_gpu.exe i get the error message "opencv error: no gpu support"!! This seems very strange! any insight on how to get away with this?

was it hard to get opencv working on GPUs please?

Oh my man! My detection Using HOG opencv is 0.8 sec/frame! not frame per sec. I think it time to buy nVidia T T (expensive). What is the video size?

I dont get it. I get hundreds of false positives whenever I try the HOG algo. Am I doing something wrong?

@dislexable not sure, I had problems with false negatives, not positives.

@c13software You didnt do anything different from the normal to get these results?
dislexable 6 months ago
@dislexable Nope, out-of-the-box was working like that.

verify that when you setup opencv before compilation cmake finds the npp library.

this video was small resolution so thats why it was going so fast. with higher resolution it slows done a bit but still was above 10fps.
getting opencv gpu working depends on your skill level. for us it was moderately difficult as no documentation or faq exists so we had to look at the source code to get things working. so if you are not scared by code, go for it, otherwise wait for official documentation. (we have some snippets on our website on how to get started)
