“Computer Vision for Artists and Designers: Pedagogic Tools and Techniques for Novice Programmers” talks about the increasingly used concept of computer vision, which refers to the ability of a computer to interpret visuals such as data, images, and videos. The article focuses on the applications of computer vision in interactive art by describing particular examples that have stood out in this field. I found Myron Krueger’s Videoplace to be a remarkable artwork that involves various aspects of vision and interaction. It gave me the impression of optical illusions, making it seem intriguing. I also thought of the concept of LimboTime to be very impressive. Involving a relatively simple idea, the project includes exciting interactivity through computer vision.
I felt the article provided a concise yet thorough understanding of the concept of computer vision. It was informative and interesting to read about the different techniques that enable the computer to infer visual data namely, ‘frame differencing’ to detect movements, ‘background subtraction’ to detect the presence of people and objects, and ‘brightness thresholding’ that compares and classifies the pixel brightness.
The discussion of computer vision in the physical world reminded me of a very common application of computer vision. The reverse camera used in cars processes visual data to such precision which enables it to produce an accurate estimate of the guide lines that assist the driver in parking the car. However, as mentioned in the article such applications are only possible if the physical conditions are designed to be compatible with the program.
Overall, the article was an engaging read. I felt it has sparked new ideas that I hope to explore in projects and further work to understand the working of the various techniques involved in computer vision.
