Project_Point_Backward(int Xproj, int Yproj, ref int Xoriginal, ref int Yoriginal)

Summary

Takes output coordinates and determines what input coordinates to use. This assumes that you have already solved for the coefficients by

Parameters

Xproj Integer representing the X coordinate of the output image to back-project
Yproj Integer representing the Y coordinate of the output image to back-project
Xoriginal Integer representing the back-projected location in the input image
Yoriginal Integer representing the back-projected location of the input image

Returns

false if the location was outside of the input image dimensions
