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.

Performing threshold operation on an RGB image

I need to perform a threshold operation on an RGB image. The thresholding that I intend to do should behave as follows. If greyscale equivalent of a pixel ( calculated as 0.299 * R' + 0.587 * G' + 0.114 * B' ) is Y, then the pixel value of the…

Replace cv::resize() with Intel Integrated Performance Primitives (IPP) resize?

I'm trying to improve surf.cpp parallel performance, and according to my analysis, a lot of time is spent at line 697: // Scale the window to size PATCH_SZ so each pixel's size is s. This // makes calculating the gradients with wavelets of size 2s…

How can IPP improve OpenCV application? And how can I integrate it?

I was wondering: How can Intel IPP make OpenCV applications faster? How can I integrate it in already written in already written OpenCV applications? I didn't find an immediate answer (this document doesn't really say much), but finally I found…

SSE Efficient signed short convolution

I am trying to implement fixed point 7X7 convolution on large signed short images (1000X1000). The (float) kernel is scaled up (by 1<<14) to get valid results, and the final results are scaled down back. I am implementing it using SSE. Working on…
