Within this workshop in the series Creative Coding with openFrameworks, we create an application that is capable of detecting objects and their color using a web cam or any other source of video input. In order to understand and follow the coding parts, some basics about images and pixels, color models, Computer Vision and OpenCV are explained and illustrated beforehand. Furthermore, we will have a look into addons in openFrameworks, commonly referred to as ofxAddons. The addon ofxOpenCv, based on the open source Computer Vision library OpenCV, will provide crucial functionalities for this coding project.
The source code (as well as complementary slides) for this openFrameworks application is online available via GitHub:
