Anisotropic filter implements the classical Coherence Enhancing Diffusion Filter [Weickert]. The plugins works on the first band of a 2D, 3D and 4D sequence. 2D and 3D algorithms are proposed. For the 3D case 2 options are available: CED 1D option is the classical filter that acts mainly on the most homogeneous structure direction; CED 2D option acts on the tangential plane of the structure.

Image segmentation by representative colors selection. Two versions are available :

• thresholding
• positive and negative colors selection and SVM learning

Coloc 2 is Fiji's plugin for colocalization analysis. It implements and performs the pixel intensity correlation over space methods of Pearson, Manders, Costes, Li and more, for scatterplots, analysis, automatic thresholding and statistical significance testing.

Coloc 2 does NOT perform object based colocalization measurements, where objects are first segmented from the image, then their spatial relationships like overlap etc. are measured. This complementary approach is implemented in many ways elsewhere.
