Web WebMar 13, 2024 · Fisheye is a non-linear transformation which for a given center pixel, distorts the pixels in the image based on the distance from the given center pixel. Essentially, pixels closer to the center receives a lot less distortion compared to the pixels which are far away. The fisheye transformation takes two parameters, center and the distortion ...
