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

From left to right : ground truth (projected), mock confocal image (projected) and thresholded pixels. 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 … Continue reading

Spindle analysis GUI

In the article “Spindle assembly on immobilized chromatin micropatterns”, we observe reconstituted meiosis spindles in live microscopy.┬áThis 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
