Abstract :
In this paper, a new oriented pattern spectrum is presented, and its properties are discussed. It can represent well the information of shape in a certain direction, which is different from that proposed by Petros Maragos, and can be properly used in shape analysis. A practical method of extracting the oriented pattern spectrum in a noisy binary image is developed, and an efficient distance function is presented to recognize different shapes with their new oriented pattern spectrums. As a practical application, the oriented pattern spectrums are used to recognize warning traffic signs on roads
