Ubuntu 16.04 or 15.10 OpenCV 3.1 Installation Guide

Build

Prepare your Ubuntu system dependencies by executing this command:

sudo apt-get install --assume-yes libopencv-dev build-essential cmake git libgtk2.0-dev pkg-config python-dev python-numpy libdc1394-22 libdc1394-22-dev libjpeg-dev libpng12-dev libtiff5-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libxine2-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev libtbb-dev libqt4-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils unzip

In Ubuntu 16.04, you can resolve dependencies (many are listed below), but the make process will fail at this moment:

sudo apt-get install build-essential cmake git

sudo apt-get install ffmpeg libopencv-dev libgtk-3-dev python-numpy python3-numpy libdc1394-22 libdc1394-22-dev libjpeg-dev libpng12-dev libtiff5-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libxine2-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libv4l-dev libtbb-dev qtbase5-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils unzip

Download OpenCV from http://opencv.org/downloads.html and unpack.

Enter the unpacked directory. Execute:

mkdir build
cd build/
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D WITH_V4L=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..
make

This completes the building process of OpenCV 3.1. (The make process does not work with Cuda 7.5 and GCC 5 in Ubuntu 16.04.)

Installation

Using make

Execute the following:

sudo make install
sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
sudo apt-get update

and reboot the system.

Using checkinstall

While you are in the build directory, execute these commands:

sudo apt-get install checkinstall
sudo checkinstall

This will create the OpenCV package that has a modern install/uninstall option.

Integration with the Caffe

Return to the Caffe directory and perform a cleanup operation with the command

make clean

(Read more here: https://github.com/BVLC/caffe/wiki/Ubuntu-16.04-or-15.10-Installation-Guide)

First, edit the Makefile.config to include the OpenCV 3.1 library like this...

OPENCV_VERSION := 3

LIBRARY_DIRS := $(PYTHON_LIB) /usr/local/lib /usr/lib /usr/lib/x86_64-linux-gnu/hdf5/serial /usr/local/share/OpenCV/3rdparty/lib/

Then, recompile the entire Caffe project.
