C. elegans embryo

This real dataset is composed of three stacks of images of a C. Elegans embryo. The deconvolution effects can be evaluated on different kinds of structures: extended objects (the chromosomes in the nuclei), filaments (the microtubules), and point-wise spots (a protein stained with CY3).
