Experimental improvements

1. Possible experimental improvements

Increase frame rate. Storage space is not a good argument, as movies can be down-sampled after analysis to save space. Eliminate possible blocks from tail or wheel Decrease reflection from bars Ensure there is an exact number of blobs on the fingers. In certain cases, 4 or 5 distinct blobs were observed, mainly due to separation of fingers.

2. Possible computational improvements

Enable to select sub-regions for different strategies. E.g. select a x-y range where aggressive merge should be used (e.g. shoulder), and another region, where aggressive split should be used (e.g. fingers).
