Digital Image Processing 指纹图像分析 . 指纹图像分析 . 公安部门借助于指纹识别系统破获案件 . 个人身份认证 将指纹信息存储与身份证中 . 入口管理 --- 重要会议入口检查 --- 多入口大型公园应用 指纹系统的应用 基于车牌自动识别的交通管理系统： --- 利用摄像头获取车牌图像 --- 图像增强处理 Adjusting the distribution of the gray level in an image --- Segmentation Segmenting letters or digitals in the plate --- Recognition Telling what the letters or digitals are (3) 交通管理 . It can be widely used to the following aspects .. Charge automatically on freeway --- Auto-record the car license plate --- Distinguish the type of car --- Recognize the plate --- Connecting the credit card system automatically (4) Traffic Control .. Park management Automatically record the car license plate and recognize it and control passing-bar to switch on or off. .. Monitor the driver with over-speed on freeway automatically record the car license plate with over-speed and recognize it. (5) Traffic Control An example --- Human face beautifying (6) Entertainment The electromagnetic spectrum arranged according to energy per photon. (2) X-ray and Visual bands of spectrum are the most familiar images in actual application, such as X-ray in medical inspection and so on. 1.10 Some examples of Using DIP Based on EM spectrum (3) Gamma-Ray Imaging Nuclear medicine: Inject a patient with a radioactive isotope that can emit gamma-ray. It is used in locating sites of bone pathology,such as infection or tumors. PET --- Positron Emission Tomograph (4) X-ray Imaging Be widely used in Medical diagnostics, Industry, Astronomy and so on. When X-rays penetrate an objects, there is a different amount of absorption for different parts in the object , so an image is generated in the film to be sensitive to X-ray energy. (5) Imaging in the Ultraviolet Band Applications of ultraviolet “light” include lithography,industrial inspection,
