Vision as an input is everywhere—and with many accelerators available to assist us. Now there is an optimized toolkit from Intel to span the hardware with a single API, and it includes a library of functions, pre-optimized kernels, and optimized calls for OpenCV and OpenVX.
Intel calls it the Open Visual Inference & Neural Network Optimization (OpenVINO™) toolkit. It’s free and open source.
The most recent release even supports a Raspberry Pi as a host to use an Intel® Neural Compute Stick 2.
