Table 9. Combinatorial approach in the image reveals 12 possible combinations. Two Thresholds (MSE <0.05 and Matrix Condition Number <300000) were implemented but the third data point (theta) is presented. Match 7 is the correct combination here for which theta (in radians) is also closest to pi/2 (~1.57).
Combinatorials = the combinatorial match which accommodated the thresholds; MSE = Mean Square Error; Condition = Matrix Condition or Matrix Number; Theta = Angle used to determine skew angle (here presented in radians).
