After reading this, I realized the way computers see things is pure math and calculations. They do not have an understanding of things like we humans do. Computers are like blank slates and for them to process anything, we have to program every single step. A computer cannot detect a person unless a programmer writes math rules to help it spot changes in pixels. I was surprised at how a seemingly simple concept like vision and tracking is actually so much more complex.
I really liked that a lot of the detection in these systems does not come from the code alone, but also from controlling the physical environment. Things like using a plain white background, strong lighting, or high contrast clothing make it way easier for simple algorithms to work well. So it is a process that requires precision both inside and outside of the code. Even a simple change in lighting or shadows can completely confuse the computer.
Also, the duality of this technology is interesting. Computer vision was originally developed primarily for tracking and surveillance. However, it later became a popular tool that artists use in interactive art. Depending on whose hands this technology is in, it can transform from an entertaining experience into something far more invasive or dangerous. It made me realize that as someone who might work with tracking tech in the future, I need to use it carefully and be mindful of where and how I use it.
