Abstract

One of the objectives of image processing is to detect and locate some meaningful discontinuities in the gray levels of an image. The usual approach taken is referred to as edge detection. Streak detection presents a related but sometimes different problem. Here we are concerned not only with the edges but also with the properties and features of that portion of the image which is contained within the boundaries of these edges. This paper looks at particular methods which may be applied for the location and characterization of such streaks and for the possible splicing together of different streak segments. Particular emphasis is placed on the development of an invariant proprerty referred to as the Preservation of Perimeter Property of an object (PPP). Coupled with this is the use of the Medial Axis Transformation (MAT) as a tool in the process. The MAT produces what is known as the skeleton of the object. Integrating a new approach to finding the Euclidean Elevation Map (EEM) with the MAT is a key in the development phases. The approach taken represents a compromise between the process of producing an exact bitmap of the skeleton and developing a faster approximation of the skeleton which incorporates usable, structural information.
