Min. Num. Around

Set the minimum required number of 3D points around each 3D point not removed as an outlier. If the number of 3D points which are not at the center of the filter but in the filter is lower than the set number, the center 3D point of the filter is removed as an outlier. If a value F was set as [Filter Size], specify a number between 1 and (2F + 1)^2 -1. The larger the value, the more 3D points are removed.
