Vehicle are always driven for long distance. The commuter chooses the bicycle as transportation for short-distance under certain circumstances, e.g., school, factory. Classify variety of different vehicles that will improving monitor capability which is important issue for traffic safety and vehicle management. That is why bicycle detection algorithm is getting more important. In this paper, a bicycle of diamond frame detector for side-view image is proposed based on the observation that a bicycle consists of two wheels in the form of ellipse shapes and a frame in the form of two triangles. Through the design of geometric constraints on the relationship between the triangles and ellipses, the computation is fast comparing to the feature-based classifiers. Besides, the training process is unnecessary and only single image is required for our algorithm. The experimental results are also given in this paper to show the practicability and the performance of the proposed bicycle model and bicycle detection algorithm.
