Homography Matrix Transformations
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 $\bf{H}$ can be viewed as a function that maps a point $(x,y)$ in an image A into another point $(x’,y’)$ in another image B. It performs the mapping, $\bf{H}: (x,y) \rightarrow (x’,y’)$, by first applying a linear combination on the input points $(x,y)$ as an affine transform...
