## Gamma distribution generator (and fitting) in Matlab… without toolboxes !

When working with confocal data, I found out that both noise and signal pixel value distribution could be very well fitted by a gamma distribution, with an offset. The pixel values were of the form Y=offset+X, where X is a … Continue reading

## Generating confocal data from ideal signal

Left: cytosim simulation of a platelet marginal band. Right : simulated confocal stack. A large issue in image analysis is to make sure that the segmentation and analysis procedure does not create artifacts or misrepresents the data in any way. … Continue reading

## Spindle analysis GUI

In the article “Spindle assembly on immobilized chromatin micropatterns”, we observe reconstituted meiosis spindles in live microscopy. This our method generates a large set of data, with many spindles, the dynamics of which we want to quantify. For this, I developed … Continue reading
