ITK Release 4/Video/HowToBuildVideoModules
There are five video modules in ITKv4 at the moment: Core, Filtering, IO, BridgeOpenCV and BridgeOpenVXL.
The first three modules(Core, Filtering and IO) do not depend on third party libraries. By default (when ITK_BUILD_ALL_MODULES is ON), the three modules are included in the build tree.
However, if you want to use BridgeOpenCV and BridgeOpenVXL, make sure you have the newer versions of OpenCV and VXl installed on your system with the following instructions:
1. Build OpenCV: We recommend to use opencv 2.4.2 or later. Get the source code using Git:
git clone email@example.com:Itseez/opencv.git git checkout 2.4.2
Use CMake to build opencv with the following configuration:
BUILD_EXAMPLES = OFF BUILD_TESTS = OFF WITH_FFMPEG = ON
2. Enable BridgeOpenCV module when configuring ITK in CMake:
Module_ITKVideoBridgeOpenCV = ON (need to manually toggle this option ON)
Then, set system library Paths for OpenCV accordingly:
OpenCV_DIR = <the path where you build the OpenCV>
1. Build VXL:
The revision number tested is 34805 ( 2012-04-23). Later version should work (not validated). Use CMake to build opencv with the following configuration:
BUILD_EXAMPLES = OFF BUILD_DOCUMENTATION = OFF
The minimum libraries needed in VXL configuration to build ITKVideoBridgeVXL are:
BUILD_CORE_VIDEO = ON BUILD_CORE_UTILITIES = ON (contains vil) BUILD_CORE_IMAGING = ON (contains vul) BUILD_CORE_NUMERICS = ON (contains vnl)
Also make sure you have FFMPEG installed that the following paths were found:
FFMPEG_avcodec_LIBRARY FFMPEG_avformat_LIBRARY FFMPEG_avutil_LIBRARY FFMPEG_swscale_LIBRARY
2. Enable BridgeOpenVXL when configuring ITK in CMake:
Module_ITKVideoBridgeVXL = ON (need to manually toggle this option ON)
Then, set system library Paths for VXL accordingly :
VXL_DIR = <the path where you build the VXL>
Currently, there is a linux nightly dashboard submission in . Search for "Ubuntu-gcc-Release-Video" on the build name.
