IJ Plugins: Filters
Fast Median - Very fast implementation of a median filter, especially optimized for 8-bit gray
level and color images, also works on 16-bit gray level and floating point. In contrast to ImageJ median filter
it uses square rather than circular window.
For instance, Fast Median filter of size 100x100 is comparable to the ImageJ's median of radius 62.
This size Fast Median filter will be over 20 faster than the ImageJ's median filter.
For larger sizes this ratio will be even larger.
Perona-Malik Anisotropic Diffusion - the classic anisotropic diffusion filter.
Coherence Enhancing Diffusion - Based on filter described in J. Weickert,
"Coherence-Enhancing Diffusion Filtering", International Journal of Computer Vision,
Vol.31, 1999, p.111-127.
Speckle Reducing Anisotropic Diffusion -
Speckle Reducing Anisotropic Diffusion (SRAD) filter based on paper:
Y. Yu and T. Acton,
"Speckle Reducing Anisotropic Diffusion", IEEE Transactions on Image Processing, Vol.11,
Plugins install under Plugins > Filters menu.
