In this paper, we present a GPU accelerated face recognition framework using CUDA. We use weighted regional LBP histograms as features and k-nearest neighbour (k-NN) algorithm for classification. Our first contribution is to present an efficient way to compute LBP values from an input image and construct weighted regional LBP histograms in GPU using a single kernel. The second contribution we make is to propose a massively parallel GPU implementation of the k-NN algorithm optimized for handling high-dimensional feature vectors. Comparisons with CPU implementations have shown that, by accelerating both the feature extraction and classification process of the face recognition algorithm, we have managed to achieve up to 29x increase in recognition speed.

Free GPU computing nodes at hgpu.org

Registered users can now run their OpenCL application at hgpu.org. We provide 1 minute of computer time per each run on two nodes with two AMD and one nVidia graphics processing units, correspondingly. There are no restrictions on the number of starts.

The platforms are

Node 1
  • GPU device 0: nVidia GeForce GTX 560 Ti 2GB, 822MHz
  • GPU device 1: AMD/ATI Radeon HD 6970 2GB, 880MHz
  • CPU: AMD Phenom II X6 @ 2.8GHz 1055T
  • RAM: 12GB
  • OS: OpenSUSE 13.1
  • SDK: nVidia CUDA Toolkit 6.5.14, AMD APP SDK 3.0
Node 2
  • GPU device 0: AMD/ATI Radeon HD 7970 3GB, 1000MHz
  • GPU device 1: AMD/ATI Radeon HD 5870 2GB, 850MHz
  • CPU: Intel Core i7-2600 @ 3.4GHz
  • RAM: 16GB
  • OS: OpenSUSE 12.3
  • SDK: AMD APP SDK 3.0

Completed OpenCL project should be uploaded via User dashboard (see instructions and example there), compilation and execution terminal output logs will be provided to the user.
