Linear structuring element of various orientations may also be used to assess local orientation of the structures. Common structuring element include squares, discrete disks and octogons. Morphological filters are defined according to a structuring element of a given size and shape. They are local filters, in the sense that they consider the neighborhood of each pixel/voxel. Morphological filters are very common filters that can be combined together to provide a large variety of solutions. Binary / label images utilities for removing or keeping largest connected component, perform size opening, fill holes, kill borders….
2D/3D measurements: photometric (intensity) and morphometric measurements such as volume, surface area, inertia ellipse/ellipsoid….Watershed segmentation + GUI, making it possible to segment 2D/3D images of (for instance) cell tissues.Morphological reconstruction, for 2D/3D and binary or grey level images, allowing fast detection of regional or extended extrema, removing of borders, hole filling, attribute filtering….Morphological filtering for 2D/3D and binary or grey level images: erosion & dilation, closing & opening, morphological gradient & Laplacian, top-hat….The library implements several functionalities that were missing in ImageJ, and that were not or only partially covered by other plugins. MorphoLibJ is a collection of mathematical morphology methods and plugins for ImageJ, created at INRA-IJPB Modeling and Digital Imaging lab. Analysis, Filtering, Segmentation, Mathematical Morphology
