Hello,

I would really appreciate some help with this problem, which is to do with working out a log polar circle value from the pixel value from the centre of an image for a foveal log polar transformation.

How do I solve for y in this equation?

ln(x/y) = y/s

Regards,
Rupert

You can solve for x as follows:

x/y = ey/s

x = y * ey/s

Now your turn....
