The input image is the gray-scale image of an aspirin card (figure 1.3.a), with one tablet missing. The objective is detecting this missing tablet by exploring the particular gray-scale characteristics of this region of the image. Note that the tablets are circular large white areas of the image. This procedure explores the gray-scale area open operator. This is a very good illustration of image segmentation without the use of thresholding.
