Algorithm Research

We were thinking whether we should use any advanced Algorithm to extract the centroid ,something like K-Mean (used for clustering) and Kristy came up with another idea to remove the requirement of putting colors on fingers. The idea is we can use a built in tool (algorithm implementation, named Snake Algorithm :) that can capture the whole object if we can point any part of it. If we can somehow detect any part of hand , the tool would gradually grow to grab the whole object. This might be good thing to do to remove the constraints of putting colors on fingers.
