opencv - HOG Detection training with CvSVM -

-

i've been looking everywhere, , cannot find tutorials on training hogdescriptor. i'm beginner hog, have used other object detection algorithms before (e.g. cascadeclassifier).

the way see it, have create cvsvm object , run cvsvm::train(), passing in vector of vectors of floats (mat), labels (1 or -1) mat, , cvsvmparams object. confused how convert cvsvm vector of floats required in hogdescriptor::setsvmdetector(). aware can use cvsvm::predict(), doesn't allow me multi-scale detection. there code available pass in trained cvsvm (or possibly original vector of vectors) , vector of floats use train hogdescriptor?

you can build own multiscale detector running cvsvm::predict() on multiple scales of same image assuming fact had same scales in training set.

i need hash algorithm produces 64-bit hash code ( long ) fewer collisions string.gethashcode() , fast (no expensive calls cryptographic functions). here's implementation of fnv still shows 3% of collisions after testing 2 million random strings. need number way lower. void main() { const string chars = "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz!#@$%^&*()_+}{\":?><,./;'[]0123456789\\"; const int n = 2000000; var random = new random(); var hashes = new hashset<long>(); int collisions = 0; for(int = 0; < n; i++) { var len = random.next(chars.length); var str = new char[len]; (int j = 0; j < len; j++) { str[j] = chars[random.next(chars.length)]; } var s = new string(str); if(!hashes.add(get64bithash( s ))) collisions++; } console.writeline("collision percentage after " + n + " random strings: " + ((doubl
