I need to implement motion blur(linear, radial and zoom )algorithms for an app I work on, like yours in GIMP. In the .c file for motion blur it is not stated which source is used for the math/algorithm. Someone knows the source, paper, book or whatever that was used as reference for implementing the motion blur algorithms? Thanks
Motion blur is convolution of the image with a straight line ; defocus blur with a filled circle. Deblurring is done by the inverse operation, deconvolution.
This can be done as multiplication in the freq domain using FFT or convolution with a simple kernel image.
