Border kill

Binary border kill morphological operation. Delete all connected components that touch the border of the image.

Overlay signals

Visualize and compare several signals by transparency display. Each signal can be translated and loaded independently.

3D height visualization

Visualize 3D volume behind the current plane. The algorithm uses a fast distance transform and gradient trick to give the impression of 3D iso-surface visualization. These work is inspired by those of Luc Vincent (see below), adapted to the visualization of a 3D volume. Take the opportunity to take a look at the other...

Compare

Use this plugin to compare two images or two volumes. Update 20190409 : support for volumes larger than 2 147 483 648 voxels.

Deleting spikes

Isolated aberrant point suppression. This plugin uses a h-maxima operator, called also contrast opening, from mathematical morphology.

Crop an image

Crop an image using graphical interface. It is also possible to precisely define the position and size of the area to be cut. Update 20180917 : adding the possibility to manually set coordinates. Update 20190510 : fixed a bug concerning selection outside the definition domain of the current image. Update 20190611...

Signal auto smoothing

The classical approaches of noise reduction do not adapt well to the variety of signals that can be encountered for different analysis methods (chromatography, XRD, Raman ...). The parameterization of these methods is often complex, with many parameters not very explicit or not intuitive and to be adapted according to...

Crop a signal

Crop a signal using graphical interface.

Resize image by splines interpolation

Image resizing by splines interpolation. See Biomedical Imaging Group of Ecole Polytechnique Fédérale de Lausannne (EPFL) for a very good tutorial concerning advanced uses of splines for image processing.

Hole filling

Morphological hole filling operation. Fills all the holes of the connected components of the image, except for the holes that touch the border.

Box filter

Local mean filter using summed area tables* for computation with o(1) complexity. *F. C. Crow, “Summed-area tables for texture mapping,” in Proc. ACM SIGGRAPH, 1984, pp. 207–212

Sphero cylinders Boolean model

This plugin generates one-scale Boolean random models of sphero-cylinders i.e. random oriented sphero cylinders located on points of a Poisson Point Process. A specific algorithm subdivides the volume and uses the properties of the Poisson point process to reduce significantly the computation time and to obtain...

LIP operations between images

Defined in 1985 by Michel Jourlin, the LIP Model (Logarithmic Image Processing) is a mathematical and physical framework dedicated to image processing. First defined as a framework adapted to images acquired in transmitted light, the interest of using LIP operators in a reflected light model has then been...

LIP edge detection

Defined in 1985 by Michel Jourlin, the LIP Model (Logarithmic Image Processing) is a mathematical and physical framework dedicated to image processing. First defined as a framework adapted to images acquired in transmitted light, the interest of using LIP operators in a reflected light model has then been...

LIP basic operators

Defined in 1985 by Michel Jourlin, the LIP Model (Logarithmic Image Processing) is a mathematical and physical framework dedicated to image processing. First defined as a framework adapted to images acquired in transmitted light, the interest of using LIP operators in a reflected light model has then been...

Flowing bilateral filter 3D

The bilateral filter plays a key role in image processing applications due to its intuitive parameterization and its high quality filter result, smoothing homogeneous regions while preserving the edges of the objects. Considering the image as a topological relief, seeing pixel intensities as peaks and valleys, we...
