In this paper the method of understanding of the cyclic object is presented. The cyclic object is a 2-D object with a hole. The proposed method of understanding of the cyclic object is part of the shape understanding method developed by the author. The main novelty of the presented method is that the process of understanding is related to the visual concept represented as a symbolic name of the possible class of shapes. The possible classes of shape, viewed as hierarchical structures, are incorporated into the shape model. At each stage of the reasoning process that led to assigning of an examined object to one of the possible classes, novel processing methods are used. These methods are very efficient because they dealt with a very specific class of shapes. This method is implemented as a module of the shape understanding system (SUS) and tested on the broad classes of shapes. The system of shape understanding is able to perform different tasks of shape analysis and recognition based on the ability of the system to understand the different concepts of shape at the different levels of cognition. The system consists of different types of experts that perform different processing and reasoning tasks. The cyclic class models and processing methods are also described.
