Detailed Description

Transforms (warps) an image based on an affine transform.

The affine transform is given as a $2\times 3$ 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 fullfil the following properties:

\[ x = c_{00} * x' + c_{01} * y' + c_{02} \qquad y = c_{10} * x' + c_{11} * y' + c_{12} \qquad C = \left[ \matrix{c_{00} & c_{01} & c_{02} \cr c_{10} & c_{11} & c_{12} } \right] \]

In other words, given matrix $C$ the source image's shape is transfored to the destination image using the inverse matrix $C^{-1}$:

\[ M = C^{-1} = \left[ \matrix{m_{00} & m_{01} & m_{02} \cr m_{10} & m_{11} & m_{12} } \right] x' = m_{00} * x + m_{01} * y + m_{02} \qquad y' = m_{10} * x + m_{11} * y + m_{12} \qquad \]
