This repository contains the material required for OpenCV demonstration. The demonstration will cover basic image processing and by the end of the demonstration we aim to write a program which can track objects based on their color and motion. It would be desirable that any person attending the workshop comes with his/her own laptop with OpenCV installed. The installation instructions are given below. Also to be able to test if the code is correctly working, it would be helpful if you bring a distinctly colored object.

The code written during the demonstration has been uploaded in the repository. The code tracks green objects by default. To begin tracking press 'T', to exit the program press 'Q'.

Installing OpenCV

Run the command corresponding to your OS in the terminal

Ubuntu, Linux Mint, Debian: $ sudo apt-get install libopencv-dev
Arch: $ sudo pacman -S opencv
Windows:
- Install the trial version of Ceemple IDE from https://www.ceemple.com/getceemple/ (preferred) Seems like the Ceemple IDE is no longer available
- OR Install OpenCV from http://opencv.org/downloads.html and configure it for any IDE of your choice
  - Visual Studio
  - Code::Blocks

The demonstration will be done using Ceemple IDE for windows and OpenCV installed on Ubuntu

Post - Installation

Linux:

Start the terminal and clone the repository, navigate to the test folder and run the Makefile

$ git clone https://www.github.com/lakshayg/opencv-demo
$ cd opencv-demo/test
$ make

Windows:

Download the repository by clicking on this link https://github.com/lakshayg/opencv-demo/archive/master.zip
Extract the zip archive and open the file test.cpp in the folder test in any IDE
Compile and run using your IDE to check if OpenCV is installed correctly

If you see a window showing the webcam output then you have successfully installed OpenCV. Press 'x' to exit.

Compiling

The .cpp files made during the demonstration can be compiled using

$ g++ file.cpp -o file `pkg-config opencv --libs`

Contact
