Making OpenCV Code Run Fast

Monday, May 1, 3:15 PM - 3:45 PM
Summit Track: 
Technical Insights II

OpenCV is the de facto standard framework for computer vision developers, with 16+ year history,  approximately one million lines of code, thousands of algorithms and tens of thousands of unit tests. While OpenCV delivers decent performance out-of-the-box for some classical algorithms on desktop PCs, it lacks sufficient performance when using some modern algorithms, such as deep neural networks, and when running on embedded platforms. We examine current and forthcoming approaches to performance optimization of OpenCV, including the existing OpenCL-based transparent API, newly added support for OpenVX, and early experimental results using Halide.
 
We demonstrate use of the OpenCL-based transparent API on a popular CV problem – pedestrian detection. Because OpenCL does not provide good performance-portability, we explore additional approaches. We discuss how OpenVX support in OpenCV accelerates image processing pipelines and deep neural network execution. We also present early experimental results using Halide, which provides a higher level of abstraction and ease of use, and is being actively considered for future support in OpenCV.
