A12 – Correcting Geometric Distortions

There are two types of geometric distortion.
1. pincushion - the image seems pinched in the middle and expanded in the boundaries.
2. barrel - the image seems bloated in the middle and pinched at the sides.

For this activity, we will use bilinear interpolation. "the graylevel v at an arbitrary location (x , y)
in the distorted image can be found using v (x , y )=ax+by+c xy+d.

We used a distored capiz window shown below,
I cropped the image
and using bilinear interpolation, the result is

Grade:
9/10 - because I think that even though I find an undistorted image. It is far from what is expected.
