Detailed Description

Transforms (warps) an image based on a perspective transform.

The perspective transform is given as a $3\times 3$ matrix C. A pixel location $(x, y)$ in the source image is mapped to the location $(x', y')$ in the destination image. The destination image coorodinates are computed as follows:

\[ x' = \frac{c_{00} * x + c_{01} * y + c_{02}}{c_{20} * x + c_{21} * y + c_{22}} \qquad y' = \frac{c_{10} * x + c_{11} * y + c_{12}}{c_{20} * x + c_{21} * y + c_{22}} \]

\[ C = \left[ \matrix{c_{00} & c_{01} & c_{02} \cr c_{10} & c_{11} & c_{12} \cr c_{20} & c_{21} & c_{22} } \right] \]
