Is there a name for 2D transformation with the least squares adjustment having the following parameters:

shift_x, shift_y, scale.

Transformation does not use any rotation... Thanks for your help.

    I wonder, if this transformation has the exact name (like Helmert...). It belongs to the group of affine transformations.2011-08-19
