Blobdetection / Brightness blobs
Dear friendly processing people,
I am starting a project where I have a camera detecting around 8 blobs that always have a static position.
The blobs have a change in their brightness. So what I do want to track the brightness of all 8 blobs, from non-visible to very bright and output this as a value which I can use. Is there an easy approach to this, or a library I can make use of? At a later point I want to analyse their colors, but for the moment brightness should be enough.
Thanks, Chris

I realize, I probably do not really need a blob detection algorithm, since they are static (the rest of the background is pitch black) What I need is an algorithm that calculates the median luminance of the pixels inside 8 circles/blobs. Anyone knows where to find this?
See Vision & video libraries.
