About

Here are some basic examples of using library OpenCV v4.5.1 writen in Visual Studio 2019. These examples were done while I was preparing my exam and project from the subject Machine vision on master studies, Department of Electronics, School of Electrical Engineering, University of Belgrade.

Installation & settings

You need the following :

1. Software: Microsoft Visual Studio 2019
2. Library: opencv-4.5.1
3. Environment Variable: OPENCV_DIR
4. System variables: Path add %OPENCV_DIR%\bin
5. Debug|x64: OpenCV_v451_dbg.props
6. Release|x64: OpenCV_v451_rel.props

List of examples

1. Read image
2. Read camera
3. Detect number of dots on dices
4. Track red circle on images
5. Affine Transformation
6. Perspective transform
7. Affine Transformation with Trackbar
