#Warp Perspective

Perspective transformation is in accordance with the object imaging projection law for transformation, that is, the object is re-projected to the new imaging plane, commonly used in visual aberration correction.

#Operator Effect

Input Image	Parameter	Output Image
	$\begin{aligned}kernel = \begin{bmatrix}0.9 & 0.05 & 15.0 \\ 0.05 & 0.9 & 15.0 \\ 0.0001 & 0.0001 & 1.1 \end{bmatrix}\end{aligned}$

#Principle

The operator maps the input picture in the form of a perspective by means of a transformation matrix parameter of size 3X3 with the following mapping relationship:

$dst(x,y)=src(\frac{M_{11} x+M_{12} y+M_{13}}{M_{31}x+M_{32}y+M_{33}},\frac{M_{21}x+M_{22}y+M_{23}}{M_{31}x+M_{32}y+M_{33}})$

Where $dst$ is the output picture, $src$ is the input picture and $M$ is the 3X3 transformation matrix.
