Process of counting weakly luminescent particles

摘要

Process and appts. for counting cells or microorganisms marked with a coloured or fluorescent stain comprises the use of a camera which accumulates photons to obtain a low resolution image (I). Starting from the threshold of this image, a binary image can be obtd. (Ib), from which a dimensional filter can be derived allowing the number of objects (N) having the same dimensions as Ib to be counted.
