Identification of the Image Definition by the Method of the Wavelet Packets
基于小波包分解的图像清晰度判定

To deal with the image definition of the micro manipulating robot under the vision servo control, a new method for the identification of the image definition is put forward, which is based on wavelet packets. As beginning, the features of the microscope system are discussed briefly. Furthermore, the advantage of wavelet packets applied in the analysis of the signal is introduced. With the analysis of the wavelet packets, the image definition eigenvector is constructed, and the linear classifier system for the image definition is established. To work out of the authority vector and threshold of the classifier system, Fisher rule is applied, which reduces the high-degree system to one-degree system. At the end of this paper, the linear classifier system is found to perform well by experiments.
