CentroidArray {cellmigRation} | R Documentation |
Create an array containing centroid data for particles identified in each frame of the imported TIFF image stack
CentroidArray(stack, lobject, threshold, dryrun = FALSE)
stack |
3D matrix loaded to workspace from .tif stack |
lobject |
Integer length in pixels somewhat larger than a typical object |
threshold |
the minimum brightness of a pixel that might be local maxima |
dryrun |
logical, shall the execution be skipped |
data.frame of centroids, with 4 columns corresponding to x-position of centroid, y-postion of centroid, brightness, and square of the radius of gyration
