Thanks Hans,
Yep, I've been working my way through the 'help' patches. I'm currently exploring pix_multiblob but it's not tracking as I thought it would. When it has an 'argument' to track 2 (or more) 'blobs', it still only tracks 1 'blob'.
Does anyone know if it's 'argument' value only relates to the amount of representations that can be applied to 1 'blob' being tracked?
Thanks, mz_multiblob ^^
