Vision for humans can vary. Some might not be able to distinguish colors properly. Others may need glasses to focus on little details, or see what is slightly farther away from them. However, one thing remains consistent, what humans see is not what they choose to see, but what is in front of them. They can’t see a pool if there is not a pool in front of them. If there is a house, they will see a house. However, a human’s vision will also vary on different factors: the brightness, the colors arounds them, the state of an individual’s eyes, and more. On the other hand, computer vision relies mostly on algorithms, pattern and feature recognition, etc. However, all of these are process, that, as described in the text, if they are low-level computer vision, they won’t even be able to resister a person or object in a video, making it flawed and susceptible to making crucial mistakes if not programmed properly. Nonetheless, this arguably shares a similar trait with humans when their vision is not 20/20, hinting that computer and human vision are both prone to having flaws.
One useful technique, aside from the others mentioned in the reading, such as keeping track of environmental conditions, patterns of pixels, and frame differencing or background subtraction, I found interesting is the example of the use of a “telecentric” lens to improve the performance of certain kinds of shape-based or size-based object recognition algorithms. I have always known that every algorithm in any computer system has a distinct role. However reading about how this lens has such a meticulous and specific task in detail has taught me the importance of each algorithm in the larger scale of aiming to achieve a successful, computer vision.
Personally, a computer’s vision capacity for tracking and surveillance can be quite effective in the use of interactive art, especially when it comes to immersive experiences. Its ability to “modify physical conditions” and capturing things such as movement or gestures can be useful to create responses to human actions which can be explore in immersive installations. Hence, like many immersive experiences, these responsive systems would allow participants to enhance the value and experience, conveying a more complex and meaningful kind of interactive artwork.
