专利汇可以提供Picture processing device专利检索,专利查询,专利分析的服务。并且PURPOSE: To measure a index microorganism in sewage treatment water with high reliability and to grasp satisfactorily a processing condition by cutting off an object candidate from a floc based upon the information concerning the curvature of the outer circumference border line of a linking area in a binary image.
CONSTITUTION: The image in which the microorganism, etc., inputted from an image pickup means 1 (television camera) is mixed is stored through an A/D converting device 2 onto a frame memory 3, the threshold of an upper limit gradiation value only is used, the area binary image is obtained from a video picture. The point that the area picture including the object microorganism appears for the first time is found, the outline of the linking area, is significant in ruggedness at the floc, on the other hand said area is smooth at the Protozoa including the object. From this point, the candidate of the object Protozoa and the lock image are cut and divided and a virtual ring is supposed on the frame memory 3. By the change of the number of intersection with the virtual ring and the noticed, label, the change point on the outline from the stem part to the body part of the microorganism is found out, the thickness of the stem and the body circumference length are calculated, the object microorganism having the stem is identified, counting is incremented and counting results are outputted from an I/O means 7.
