Tablet counting machine base on image processing

Abstract

This paper proposes Tablet counter machine base on image processing. A digital webcam creates an image of drug being dispensed. This image is displayed in standard MGB model. The original image will change to grayscale image. Then grayscale image will filtered for noise using a median filter and then using threshold we obtain a digital binary image of the pill being dispensed. The image is further processed using erosion and dilation. The actual number of drug in the image is determine by applying connected component labeling and centroid process. Our experiment used 6 mm. to 12 mm. samples with accurate results. ©2012 IEEE.
