In this repository, you can find a small project I did during my Master degree. In this application, I use interest points to compare features descriptors from the webcam with the ones from a still image (image 1). If image 1 is placed in the webcam field, the application will detect it and replace it with Image 2.
.\bin\ImageDetection.exe -i .\exemples\image1.jpg -i .\exemples\image2.jpg
