How to create a video from multiple images

Hi! If you work with computer vision maybe you have had the need to generate a video from a sequence of images, in order to get a dynamic view of your results. I'm going to show you a very easy way to do that with a simple command, using ffmpeg :) .

How to use OpenCV with CMake and Codeblocks on Ubuntu

Continuing the previous posts on How to Install OpenCV 2.3.1 in Ubuntu 11.10 Oneiric Ocelot with Python support and How to use CMake ith OpenCV now I'll show you how to use both OpenCV and CMake with Codeblocks IDE. Codeblocks is an open source, cross platform, free, great C++ IDE built to meet the most demanding needs of users. It is very extensible and fully configurable. I have been using codeblocks for about 2 years and I never felt the need to change to another IDE. It supports debugging and code completion which are very useful features.

How to use CMake with OpenCV

CMake is a cross platform, open-source build system. It consists in a family of tools designed to build, test and package software. It is used to control the software compilation process using simple platform and compiler independent configuration files. CMake generates makefiles that can be used in the compiler environment of your choice.

OpenCV is an open-source computer vision library which was already mentioned in this blog (see How to install OpenCV 2.3.1 in Ubuntu 11.10 Oneiric Ocelot with Python support).

This "how to" will guide you through the process of using CMake to compile and build OpenCV projects. It is based on the tutorial made by Damiles but has some minor changes.

How to install OpenCV 2.3.1 in Ubuntu 11.10 Oneiric Ocelot with Python support

OpenCV (Open Source Computer Vision) is a library of programming functions for real time computer vision. It is written in C/C++ and is used worlwide in many computer vision applications.

This "how to" is a mix of two other great tutorials on OpenCV installations: A Compreehensive Guide to Installing and Configuring OpenCV 2.3.1 on Ubuntu from ozbots.org; and the OpenCV Installation Guide on Debian and Ubuntu from the OpenCV Wiki. I used this procedure to successfully install OpenCV on two amd64 computers (a laptop and a desktop) running Ubuntu 11.10 Oneiric Ocelot. However, if you find any problem you can check the Comprehensive OpenCV Installation Troubleshooting Guide from ozbots.
