Re: [OctDev] imrotate

[Jeff O. <jj...@cs...>]

I have implemented some image processing routines for graylevel images. 
There is no RGB-smart wrapper yet... just routines that operate on float 
matrices. They are all .m scripts, so they are not optimized. They also 
make heavy use of the fft routines.

imtranslate uses the Fourier shift theorem to apply a translation using 
Fourier resampling.

imshear also used the Fourier shift theorem.

imrotate is am implementation of the shearing method of Paeth to apply 
rotations using Fourier resampling. This routine uses imtranslate, 
imshear, and rot90.

Feedback?
