HullkGround: Background subtraction by convex hull estimation
Participant : Charles Kervrann.
The HullkGround software (APP deposit number: IDDN.FR.001.400005.000.S.P.2009.000.21000) written in java (plug-in ImageJ (http://rsbweb.nih.gov/ij/ )
decomposes a fluorescence microscopy image sequence into two dynamic
components: i/ an image sequence showing mobile objects; ii/ an image
sequence showing the slightly moving background. Each temporal signal
of the sequence is processed individually and analyzed with
computational geometry tools. The convex hull is estimated
automatically for each pixel and subtracted to the original
signal. The method is unsupervised, requires no parameter tuning and
is a simplified version of the
