ABSTRACT:
The image of microorganisms contained in a sludge of an aeration tank is picked up by an image pickup device having the function of magnifying and picking up microorganism images. Binarizing processing is then made to obtain a binarized image from the resulting gray image, and the binarized image is subjected to thinning processing. The number of pixels of the image left after often the thinning processing is counted to measure the amount of filamentous microorganisms. In this manner, the amount of the filamentous microorganisms can be measured accurately irrespective of their thickness.
