Line 42:

GST represents the direction along which the image <math>f</math> can undergo an infinitesimal translation with minimal (total least squares) error, along the "lines" fulfilling the following conditions:

1. The "lines" are ordinary lines in the curvilinear coordinate basis <math>\xi,\eta</mahtmath>

<math> \begin{align}\cos(\theta) \xi(x,y)+\sin(\theta) \eta(x,y)= Constant \end{align}</math>
