histogram-of-oriented-gradients-gpu's Introduction

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
