How to simulate fisheye lens effect by openCV?
I am looking for ways to create fisheye lens effect, looked at documentations for openCV, it looks like it contains Camera Calibration functions for radial distortions like fisheye. Is it possible to simulate fisheye distortion by openCV? If it is possible to do it by openCV, comparing to openGL, which one will generate better results? Thanks. I created this app using opencv. Is this the effect you are referring to? I basically coded the formula shown on wikipedia's "Distortion(optics)" I can show the code if needed Update : OK, so below is the actual code written in c++ using opencv (not
