We are living in a time when smartphones can capture exceptional photos, but the existence of digital photos and the technology behind their functionality are often taken for granted. Therefore, I created this presentation to introduce the fundamentals of how a computer can display a picture (i.e. pixels, light and shadows, and RGB representation of colors). The presentation also includes a challenge for the student audience to come up with a way to create a black and white filter for photos. At the end of the presentation, I show off some photo manipulation techniques in MATLAB as practical examples to demonstrate the "behind the scenes" of what usually is a single tap on smartphones. I hope this activity can inspire young students' curiosity and motivate them to start asking "why" and "how" when they interact with technology.
I love this post, this is a great way for students to get excited about subjects like computer vision and computer graphics!
