affine transformation

Understanding the Homography Matrix The homography matrix describes the relationship between 2 camera images that observe the same plane. It tells you how points in image A are transformed and can be located in image B. The homography matrix $\mathbf{H}$ can be viewed as a function that maps a point $(x,y)$ in an image A into another point $(x^{\prime },y^{\prime })$ in another image B. It performs the mapping, $\mathbf{H}\mathbf{:}\mathbf{(}\mathbf{x}\mathbf{,}\mathbf{y}\mathbf{)}\to \mathbf{(}{\mathbf{x}}^{\prime }\mathbf{,}{\mathbf{y}}^{\prime }\mathbf{)}$, by first applying a linear combination on the input points $(x,y)$ as an affine transform...
