So how does QuickBlobs stack up? It is written in C and is extremely light weight, compiling to less than 5KB as a library or 15KB as an executable. The worst case memory use of the algorithm is O(sqrt(n)) and a 10 thousand pixel wide image needs (in theory) 600KB. QuickBlob is naturally fairly quick. My low end 1.6GHz laptop can do a 4k by 4k image in just 0.4 seconds. Benchmarks suggest that a 640x480 x 30fps video stream with around 100 blobs in each frame could be processed in real time on a single 1GHz ARM core. Finally it is licensed LGPL, so you can use it freely in your applications.
