Celer: Cells analyzer
What is Celer ?
Celer is a half-automated plugin used to analyse the geometry of cells (lumen size, wall thickness,…) provided by light microscopic images. The study process only the sharp parts of the image: these parts are automatically detected by the application. The numerical results are saved in csv files, easily readable on spreadsheet
At left, Albies Alba – O. Martin (2010) ; at right, Pinus Kesiya – Y. Caraglio (2007). The white edges show the limits between cells, the red contours the lumen border of the best cells.
Celer will not provide successful results in the following cases:
on winter wood, where the lumen is smaller and darker ; when the color properties are reversed, the cell detection is very bad, as shown on the opposite side (Albies Alba – O. martin 2010).
on non colored images, where the contrast between walls and lumen are not strong enough, as shown on this image (Spruce – C. Rathberger 2009)
- The winter wood processing,
- The mixed image, containing summer and winter wood,
- The non colored images processing
to have batch image processing tool, we have to rather use the C-Toaster plug-in
Description: magnification, sharpness factor, threshold on thickness standard deviation,wall thickness (average, median, maximal, minimal or all values)
