Counting of yeast colonies in Petri dish images
Description
The package contains demo of counting the yeast colonies in images of Petri dishes. The algorithms, contained in this demo, represent part of a software tool used to determine relative coverage of the dish, to estimate the number of colonies, and, using simple graphical tool, to correct this estimate.
The algorithms, contained in the package, perform the necessary preprocessing of an image and estimate the count of colonies. Included are several filters to reduce the estimation noise, separation of round, isolated colonies from the conglomerate blobs and estimation of number of colonies in these conglomerates.
The output of the demo are two images: the original (grayscale) image with markings of the dish center and the region-of-interest and the image of the region-of-interest, with crossmarks for the counted colonies and with the figures of relative area and the estimated number of colonies.
