MIVisionX toolkit is a set of comprehensive computer vision and machine intelligence libraries, utilities, and applications bundled into a single toolkit. AMD MIVisionX also delivers a highly optimized open-source implementation of the Khronos OpenVX™ and OpenVX™ Extensions.


The AMD ROCm Augmentation Library (rocAL) is designed to efficiently decode and process images and videos from a variety of storage formats and modify them through a processing graph programmable by the user. rocAL currently provides C API. For more details, go to docs page.

Supported Operations

rocAL can be currently used to perform the following operations either with randomized or fixed parameters:

Blend Blur (Gaussian 3x3) Brightness Color Temperature
ColorTwist Contrast Crop Crop Mirror Normalization
CropResize Exposure Modification Fisheye Lens Flip (Horizontal, Vertical and Both)
Fog Gamma Hue Jitter
Lens Correction Pixelization Raindrops Random Crop
Resize Resize Crop Mirror Rotation Salt And Pepper Noise
Saturation Snowflakes Vignette Warp Affine


Build instructions

rocAL builds and installs as part of the MIVisonX toolkit. rocAL depends on the AMD’s ROCm Performance Primitives (RPP) library, and it needs to be installed for rocAL to build. rocAL also needs the Turbo JPEG library to decode input JPEG images.

  1. Make sure to have the AMD’s RPP library installed. Please refer to the RPP’s page for instructions on how to install RPP.
  2. Make sure you’ve installed the Turbo JPEG library version 2.0 or later, refer to the section below.
  3. Refer to the MIVisonX page and follow build an installation steps (Build & Install MIVisionX).

Turbo JPEG installation

Turbo JPEG library is a SIMD optimized library which currently rocAL uses to decode input JPEG images. It needs to be built from the source and installed in the default path for libraries and include headers. You can follow the instruction below to download the source, build and install it. Note: Make sure you have installed nasm Debian package before installation, it’s the dependency required by libturbo-jpeg.

 sudo apt-get install nasm

Note: You need wget package to download the tar file.

 sudo apt-get install wget
git clone -b https://github.com/rrawther/libjpeg-turbo.git
cd libjpeg-turbo
mkdir build
cd build
      -DCMAKE_INSTALL_DOCDIR=/usr/share/doc/libjpeg-turbo-2.0.3 \
make -j$nproc
sudo make install

LMDB installation

sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev
