Using computer vision to generate visuals.
Using openFrameworks I wrote an application that analyzes video and generated these still vector images based on specific image processing. Within OF, I used the OpenCV library to detect a singular blob in the video. In this case, it is a hand. As the hand moves up, down, left or right (x + y axis’), a line is drawn with a thickness relative to speed. This line is the red color in the images. the dark and light grays are ellipses and curves that are controlled by the direction and speed of the blob. Any video would generate a completely unique image, and I plan on creating a series of these based on more conceptual source material.
