Questions related to Intel Integrated Performance Primitives (IPP), a multi-threaded library of functions for multimedia and data-processing applications.

Intel Integrated Performance Primitives (Intel IPP) is an extensive library of "algorithmic building blocks" for multimedia, data-processing, and communications applications. It supports multiple threads and has been highly optimized for Intel-family microprocessors, making extensive use of SIMD instructions (e.g., MMX, SSE, and AVX). The Windows, Linux, Android, and macOS environments are supported.

The library supports a wide range of functions for various domains and also provides for an OpenMP configuration, which can allow certain functions to run on multiple cores.

How do I invoke ippiOpticalFlowPyrLK_16u_C1R?

The examples that I'm basing my work on use unsigned char image; I have 16-bit unsigned images. Doing the naive substitutions of u8 -> u16 in the IPP function names doesn't work (I get compiler errors in some of the type casts). Does anyone have a…
