Introduction
OpenVX* is a standard from Khronos*, offering a set of optimized primitives for low-level image processing and computer vision primitives. The OpenVX specification provides a way to write code that is portable across multiple vendors and platforms, as well as multiple hardware types.
Intel® Distribution of OpenVX* is delivered as part of the Open Visual Inference & Neural network Optimization (OpenVINO™) toolkit, which is a software development package for development and optimization of computer vision and image processing pipelines for Intel System-on-Chips (SoCs), and provides the following key features:
- Performance
- Intel® Distribution of OpenVX* Implementation offers CPU kernels which are multi-threaded (with Intel® Threading Building Blocks) and vectorized (with Intel® Integrated Performance Primitives). Also, GPU support is backed by optimized OpenCL™ implementation.
- To perform most read/write operations on local values, the implementation supports automatic data tiling for input, intermediate, and output data.
- Extensibility
- The SDK also extends the original OpenVX standard with specific APIs and numerous Kernel extensions. Refer to the Intel's Extensions to the OpenVX* Primitives chapter for details.
- The implementation also allows you to add performance efficient (for example, tiled) versions of your own algorithms to the processing pipelines, refer to the Intel's Extensions to the OpenVX* API: Advanced Tiling chapter on the CPU-efficient way and the Intel's Extensions to the OpenVX* API: OpenCL™ Custom Kernels chapter for GPU (OpenCL) specific info.
- Heterogeneity
- Support for both task and data parallelism to maximize utilization of the compute resources such as CPU and GPU.
- General system-level device affinities, as well as fine-grain API for orchestrating the individual nodes via notion of the targets. Refer to the Heterogeneous Computing with Intel® Distribution of OpenVX* Implementation chapter for details.
New and Changed in the Release 1
Executive Summary
- Removal of Khronos* Neural Network extensions and CNN-related Intel Extensions.
- Removal of samples that had previously used Khronos* Neural Network Extensions, as well as samples that had dependence on OpenCV.
