working with fastHOG; moving towards fast object detection

July 9, 2013 Leave a comment

Although HOG calculations don’t take much portion of time when running object detectors, but the dot products do. Sending HOG pyramid to the GPU steals away all the benefits of calculating dot product on GPU, only way is to calculate HOG also on GPU for different scales of pyramid.

Therefore I am trying to fastHOG. It requires quite a bit of libraries.

one of the libray is FLTK

if you don’t want to put it in the default location (which might be restricted) the following will help make install prefix=New_Dictionary_location

or you can set up through configure file

./configure –bindir=/location/fltk/bin –libdir=/location/fltk/lib –includedir=/location/fltk/include/ –prefix=/location/fltk

GLSL Texture

Coordinates of the gl_TexCoord[0]

gl_TexCoord[0].t —— rows

gl_TexCoord[0].s ——cols

vec4 x = texture2D(textureX, vec2(Columns, rows));

gl_FragColor = x;
