Barrel distortion is a divergence from the rectilinear projection in geometric optics where image magnification decreases with increasing distance from the optical axis.

In telecommunication, the term optical axis has the following meanings: 1. ...
The visible effect is that lines that do not go through the centre of the image are bowed outwards, towards the edge of the image.
Shouldn't it rather be: 'bowed inwards'? Pincushion Simulation Pincushion distortion is a divergence from the rectilinear projection in geometric optics where image magnification increases with increasing distance from the optical axis. ...
The spherical distortion and its inverse can be readily implemented and applied in J. A script with these barreldistortion functions and a cover form is available from [6].
While the software at [3] is faster than the functions described here, we have developed simple and effective tools for removing barreldistortion in J. One of the advantages of the J tools is that the source script is available, ready for modifications and improvements.
