To me a particle is a set of 8-connected component, with or without hole. It can have anyshape like this: http://dip4fish.blogspot.com/2011/04/detecting-branched-points-in-skeleton.h.... The aim i then to analyse the skeleton and the contour of the particle:http://dip4fish.blogspot.com/2011/06/open-curve-to-ordered-pixels-second.htm... I was wandering if there was something like scikits.image.thin( binaryparticle) could be directly done. Jean-Patrick Le , Maël Primet a écrit :

what do you mean by particle? round? you would want to detect the center then? skeletons will probably not be appropriate in this case because they are sensible to noise. There are many existing skeleton algorithms, either using simple morphological operations,

distance transforms or EDP, but to my knowledge none have been implemented in this package.

Hi,

Using scikits.image, is it possible to get the skeleton of a binary 2D

particle ?

Best regards
