Intel® IPP 2017 is now available. This release added new Platform-Aware APIs to support 64-bit parameters for image dimensions and vector length, significantly improved performance of zlib compression functions, and extended optimization for different platforms.
What's New in Intel® IPP 2017:
Added Intel® IPP Platform-Aware APIs to support 64-bit parameters for image dimensions and vector length on 64-bit platforms and 64-bit operating systems:
I have an implementation for Image Warp using the ippiWarpAffineLinear and related set up functions. The implementation works great and gives the right results.
But, I get a difference in results between when-
- input is aligned to 64.
- unaligned input.
This is *not* seen with the ippiWarpAffineNearest symbol.
I have attached the warped image and the diff'ed warped image between aligned and unaligned input.
Here are the questions that I have-
I have a implementation of image rotation in IPP 9.0 using ippiWarpAffineNearest symbol. This implementation works great except for the following case where the results on AVX2 and SSE4 machines do not match-
Image Size - Multiples of 256
Rotation angle - 45, 135 degrees
Data Type - uint8
Destination image size = Source image size
I am new to C++. I am using Intel's IPP for resizing an image in VS2015. I am trying to use ippiResizeLanczos_8u_C3R function to resize the image.
I do not know how to see/view the resized image or get the pixel values of the resized image(image after applying the above mentioned function), as I intend to use the resized image for further processing. The function perhaps returns only the "IppStatus". But I want to get the resized image or the data information(pixel values) of the resized image as return value.
Any help in this regard would be highly appreciated?
I'm using Intel IPP 8 (On the latest 2015 Edition of Composer).
Intel IPP offers Min / Max Filters and Erode / Dilate Filters.
One could use Erode (With all 1 Mask) for Min and Dilate (With all 1 Mask) for Max.
Yet, what I'm curious about is how come Min / Max aren't faster than Erode / Dilate?
Since they are "Private" cases I would assume they can be much farther be optimized.
Could anyone comment on that?
Does any of them benefit from using the Multi Threaded library?
I am trying to narrow down an annoying problem related to download of IPP libraries.
I am trying to download the IPP for Windows (community edition) library installer over the web. However, the download keeps getting interrupted every 30 seconds and the download rate keeps going to zero. It starts after sometime and continues for a while, but then stops again. This continues for quite some time until the download fully stops before completing.
We are using USCI - Unified Speech Codec Interface from an old version of IPP (ComposerXE-2011). What is the latest version of IPP or Composer-XE that includes USCI?
Are there lot of USCI related changes from version 2011 to the latest?
I'm currently using IPP (2017) on Linux, so far it behaves relatively well, but there is something that remains cryptic to me:
How do I determine which library to link based on the current configuration?
Right now I have this installed:
