In many areas of commerce, government, academia, and hospitals, large collections of digital images are
being created. Many of these collections are the product of digitizing existing collections of analogue photographs,
diagrams, drawings, paintings, and prints. Usually, the only way of searching these collections
was by keyword indexing, or simply by browsing. Digital images databases however, open the way to
content-based searching. In this paper we survey some technical aspects of current content-based image
retrieval systems.

说明: 采用Laser - PVDF 实验系统对纳米AlP/ SiO2 中激光超声信号进行采集. 利用小波的多尺度分解、重
构和消噪功能,提取出直达波及其反射回波,测量了时间间隔和纳米AlP/ SiO2 的纵波声速. 结果证明小波变换
的方法能有效地处理复杂激光超声信号.(Using Laser- PVDF experimental system of nano-AlP/SiO2 Laser ultrasonic signal acquisition. Using wavelet multiscale decomposition, reconstruction and de-noising function, extracted from direct wave and its reflection echo measured time interval and nano-AlP/SiO2 of the longitudinal wave speed of sound. wavelet transform results show that the method can effectively deal with the complexity of laser ultrasonic signals.)
