In the previous project, we have discovered how inverse warping can be used to transform an image using projections. In this project, we use projective transformation to change the viewing angle of the image and rectify. An application of this can be mosaicing image as well, which creates a kind of panoramic image.

Homography refers to the matrix that allows the projective transformation from one image to the other image. And for use, this is used to change the viewing angle. Solving the following matrix for h vector will give us the necessary points for homographies.
