ABSTRACT
This chapter covers two related image analysis tasks: object detection by pattern matching and shape detection using Hough transform techniques. One of the most fundamental methods of detecting an object of interest is by pattern matching using templates. In template matching, a replica of an object of interest is compared to all objects in the image. If the pattern match between the template and an object in the image is sufficiently close (e.g., exceeding a given threshold), then the object is labeled as the template object.
