[An attempt of applying the image processing for the automatic estimation of sampled airborne pollen].
Development of techniques to rapidly and easily estimate an airborne pollen quantity is necessitated in order to make out a appropriate prescription for an allergy patient from medical clinical viewpoints, and in order to research a movement of allergen from medical basic viewpoint. The measurement of airborne pollen quantity required a large labour and time, because the amount of pollen grains is visually measured by naked eye. This paper, as a first step to estimate an airborne pollen quantity full-automatically, discuss techniques to measure the quantity of sampled airborne cedar pollen automatically and rapidly using the image processing techniques. As a result, the following facts are cleared. Automatic measurement is possible to some degree without any special image processing. It is important to eliminate a noise on image as blurs on basefilm for high accuracy measurement. The precision has improved fairly with level correction for image. Sharpening filter is the most appropriate process to improve the accuracy of automatic measurement of sampled airborne pollen. This filtering process has a merit that the operativeness is easy.
