Getting rid of the irrelevant, singular points

Red Cloud



Take some time to look at the picture above. We can notice a red cloud. There's a red dense cloud and some irrelevant red points around that red cloud.



Suppose the red cloud to be the set of vector $V = {v_1, v_2, ..., v_n} subset mathbb{R}^3$. How can I get the dense cloud from $V$? In other words, how can I get rid of the irrelevant points around the dense red cloud?
