MM3 can use either deep learning or a traditional machine vision approach (Otsu thresholding, morphological operations and watershedding) to locate cells from the subtracted images. For info on the deep learning-based segmentation widget, see SegmentUNet.
The following four parameters are important for finding markers in order to do watershedding/diffusion for segmentation. They should be changed depending on cell size and magnification/imaging conditions.
OTSU parameters
first_opening_size
: Size in pixels of first morphological opening during segmentation.distance_threshold
: Distance in pixels which thresholds distance transform of binary cell image.second_opening_size
: Size in pixels of second morphological opening.min_object_size
: Objects smaller than this area in pixels will be removed before labeling.
