RotateImage

Image rotation performed by 3 separable skews

Description

The rotation performed is the 3 pass separable rotation using FFT-based methods to perform the skews. Aliased spectral components are masked after EACH skew along with some lowpass filtering to reduce ringing.

• Required Products: Image Processing Toolbox
• MATLAB release: MATLAB 5.2 (R10)

Your example doesn't work!

It's helpful for principal confirmation.

Hi, Val. Would you try the following change:

mask = conv2(mask,ones(Nx,Ny)/(Nx*Ny),'same');
->
mask = conv2(double(mask),ones(Nx,Ny)/(Nx*Ny),'same');

In my environment(win xp, R200b + IP toolbox), it works well.
