Blob finding algorithm
This video describes an algorithm that is one way to identify and compile statistics about regions within a video that you are interested in. Specifically, it talks about how to identify regions of color. This is a high-level video that doesn't go deeply into code. Instead, it describes the algorithm visually.
Note: I have a mistake in this video but am not finding an easy way to fix this in Youtube. I'll re-edit the video soon. In the video I say that saturation is found as the maximum RGB value minus the minimum RGB value but that is wrong. It is actually (maxRGB - minRGB)/maxRGB. It is a slightly different formula but makes a big difference.
