Line 99:
• First Phase :
• Divide the area of search in four [[quadrant (plane geometry)|quadrant]]s
• Start search with three locations, one at center (A) and others (B and C), S=4 locations away from A in orthogonal directions
• Find points in search quadrant for second phase using the weight distribution for A, B, C:
• If (MAD(A)>=MAD(B) and MAD(A)>=MAD(C)), select points in second phase quadrant IV
Line 116 ⟶ 115:
• Select the ___location with lowest weight as motion vector
SES is computationally very efficient as compared to TSS. However the peak signal-to-noise ratio achieved is poor as compared to TSS as the error surfaces are not strictly unimodal in reality.
