This class consider the SRT (scale, rotation, translation) warping model with parameters such as
with the scale, the rotation, and the translation along u and v axis in the image.
We recall that u axis is the image horizontal axis, and v axis is the image vertical axis. A point (u,v) with coordinates (0,0) is located in the top left image corner.
