Geometric Feature-Based Pattern Matching

Pattern matching is a method for finding the instances of a pattern in matching image. It can analyze an object image relating to a model. In our method, we use a model to represent the pattern which includes many sample points. Each sample point is distributed evenly along the edges. When matching is over, we have a list of results with scores. Each score means the similarity between the pattern and the results. Then, we compare these match scores with an appropriate threshold to decide the results are true or not.
