CELL COLONY REGION IDENTIFICATION DEVICE, CELL COLONY REGION IDENTIFICATION METHOD, AND RECORDING MEDIUM

摘要

In the present invention, by deleting small regions from an initial boundary image, a provisional boundary image is obtained (step S211). The provisional boundary image is thinned and shaped, and is subjected to a thickening process to obtain a mask image (steps S212-S214). An updated provisional boundary image is obtained by masking the initial boundary image with the mask image (step S215). In the updated provisional boundary image, adjoining end points are connected (step S216). Broken boundaries are repaired by repeating the steps S212-S216. As a result, cell colony regions can be easily and efficiently identified even if cell colony boundaries are blurred.
