The application of simple shape measures based on a Minimum Bounding Rectangle to the General Shape Analysis problem

This paper deals with the problem of General Shape Analysis. Simple shape measures based on a minimum bounding rectangle are investigated so as to obtain and compare general shape characteristics. The goal of General Shape Analysis is to find for each test object the one or few most similar templates. Thanks to this we can determine general information about a shape, such as how rectangular it is. Our work involves trying to find a shape descriptor that is simple to derive, allows for fast matching, and is the most consistent with a human benchmark that has been collected from the appropriate inquiry forms. Some experiments using various simple shape mea- sures were performed. A concise explanation of these experiments and some percentage accuracy results are provided in this paper.
