One thing I found interesting about the reading was the difference between how humans and computers see. I was not completely surprised that computer vision has more limitations because, at the end of the day, computers interpret information numerically. Even when we write code using programming languages, it eventually has to be translated into something the computer can process. What I found more interesting was the idea that instead of only improving the algorithm, we can change the physical environment to make it easier for the computer to see. Techniques such as background subtraction, brightness thresholding, and frame differencing depend on things like contrast, lighting, and movement. Computer Vision for Artists and… At first, I wondered how changing the environment would help when the computer still has to translate what it sees into data either way. However, I think the point is that these changes make that data easier to distinguish. For example, making a person stand out strongly from the background gives the computer clearer differences in brightness or color to work with. I found it interesting that sometimes changing the environment can be more effective than simply making the software more complicated.
I also think computer vision creates an interesting relationship between interaction and surveillance. Tracking someone’s body can make an artwork feel much more interactive because the body itself becomes a way of communicating with the system and receiving feedback from it. I could imagine experimenting with something like this myself. I have seen a musical work where artists used Wii remotes to affect sound through their movements, and computer vision could create a similar interaction without necessarily relying on a traditional controller. At the same time, I think there is an important ethical boundary. The reading shows that computer-vision artworks can track willing participants as well as people who are unaware that they are being observed. Computer Vision for Artists and… I would be comfortable interacting with an artwork that tracks me as long as I am informed beforehand, especially if there are clear rules about what happens to the data being collected. Tracking people without their knowledge crosses a line for me, even if being unaware is supposed to be part of the artistic experience. Computer vision can make interactive art more responsive and interesting, but I don’t think creating an experience should come at the cost of the participant’s awareness or consent.
