One of the differences I observed was basically the flexibility of human vision compared to computer vision. Generally, we are able to identify people, objects, and occurrences without really thinking about it that much, even when there is a change in lighting and backgrounds. On the other hand, computer vision is dependent on certain conditions and rules. This means that when there is an extensive change in lighting or an object merges with the background, then the computer will not be able to detect it effectively. The reading also helped me understand that computers do not interpret what they are seeing, they just analyze pixels, movement, luminosity and contrast.
There is one method called background subtraction where the computer compares the current video with a picture of the empty background in order to find out what has been changed. As it was mentioned in the reading, “areas which are very different from the background are likely to represent objects of interest.” In other words, if there is a person appearing in the frame, the computer will be able to identify that some areas of the picture are different from the original empty background and that would make it easier to track its movement.
I believe that computer vision enhances the interactivity of art since the art piece will interact with your actions in terms of position, movement, and other factors. But at the same time, it can feel a little weird due to the fact that it feels like you are being watched and tracked. I believe that computer vision adds individuality to the experience, since art pieces will react to the actions of each person individually. This brings out the idea of individuality, surveillance, and privacy.
