Histogram of oriented gradients GPU

Implementation of HOG (histogram of oriented gradients) on GPU using OpenCL

Example

$ ./hog input [device] [load] [train] [visual]

• input: use --input 'path_to_image' or --video 'path_to_video'
• device: specify device as --device GPU or --device CPU (CPU is implicit)
• load: load linear SVM model --load 'path_to_model'
• train: train new model --train 'path_to_positive' 'path_to_negative'
• visual: visualize HOG features --visual
