Region mathematical feature computed as sum of region pixel coordinates Region moments are regions' mathematical features computed as sums over region pixels, where \(p_x\) and \(p_y\) denotes x and y coordinate of a pixel.

Values of this enumeration:

• _02 - \(Moment_{2,0}(R) = \sum_{p \in R} p_x^2\)
• _11 - \(Moment_{1,1}(R) = \sum_{p \in R} p_x p_y\)
• _20 - \(Moment_{0,2}(R) = \sum_{p \in R} p_y^2\)
