WebSep 7, 2010 · This function NLMF performs Non-Local Means noise filtering of 1D signal, 2D grey/color or 3D image data. The function is partly c-coded for cpu efficient filtering. Suitable for almost every image data type such as MRI, CT and normal photos. Warning !, Image filtering removes noise, but important (medical) details can also be lost, (see ... Webmedfilt2 supports the generation of C code (requires MATLAB ® Coder™).Note that if you choose the generic MATLAB Host Computer target platform, medfilt2 generates code that uses a precompiled, platform-specific shared library. Use of a shared library preserves performance optimizations but limits the target platforms for which code can be generated.
