Table of flood histogram formulae

Anger’s equations:
Xa=(A+B)(C+D)A+B+C+D,Ya=(A+D)(B+C)A+B+C+D.
Zhang’s method:
Xb=ACA+Ccos(π/4)+BDB+Dsin(π/4),Yb=ACA+Csin(π/4)BDB+Dcos(π/4).
Adaptive method: Xc = αXa + (1 − α)Xb, where α ∈ [0, 1],
Yc = αYa + (1 − α)Yb.
In magnetic field: Xd = Xc cos (θ) + Yc sin (θ),
Yd = −Xc sin (θ) + Yc cos (θ).
