I need motion blur algorithms for a small image editing app. Can you point me to some resources, books or papers or maybe code examples?

Which resources does GIMP use for this math?

Thanks

  • An example can be seen in this [SO](http://stackoverflow.com/questions/1602988/convolution-matrix-for-diagonal-motion-blur) question. – Maurits Jul 13 '12 at 13:11

  • Hmm really it is just a convolution with a mask? I thought it is much more complex? What about Zoom and Radial blurs? http://docs.gimp.org/2.6/en/plug-in-mblur.html You calculate a different mask for each pixel? – user1509260 Jul 15 '12 at 21:16
