In this s paper, a. novel wavelet based corner Detecting algorithm is proposed. Some intrinsic indicators implied in corners are extracted by utilizing the wavelet, transform. Since these indicators are independent, of the corner angle and corner curvature, they can be used to detect, corners. In addition, several properties of corners in the multiscale wavelet transform are introduced. By applying these indicators and properties, corners can be detected correctly and efficiently. The experimental results show that our algorithm achieves better accuracy than the conventional single-scale corner detected. On the other hand, our algorithm is more computationally efficient. and casier in implementation, than other multiscale corner detectors.
