ippiHOG_ location array question

Ricardo_O_ — Wed, 07 Dec 2016 12:48:03 GMT

Hi,

When using the ippiHOG_<mod> function, what should the input parameter "IppiPoint* pLocation" contain?

The center of the windows where the Hog descriptors are to be calculated or the upper left corners of these windows? It is not clear in the documentation.

Regards,

Ricardo Oliveira

Dear customer,

Well, in the example of HOG.c, the fist element of pLcation is {0,0}, it probably should be left top corner of window. This function actually has similar processing with OpenCV, you could refer openCV's doc about HOG object detect function. In openCV's guide, the location is left-top corner points. Hope it would be helpful to you.

Best regards,
Fiona
