Experts say that automatic face recognition systems, in which a computer attempts to recognize an individual by checking his or her face against thousands of images stored in the a database, are gaining in popularity but are not very reliable. They There won’t be image a matchof if the person’s face is not contained in the database, or image a match maybe overlook of if a picture that is in the database looks efficiently sufficiently different than the individual standing in front of the system’s electronic eye. Experts say that’s because the stored photograph maybe several years old in and bear little resemblance to the individual or the pose or lightlike maybe different. Cycologist Psychologist Rob Jenkins of the University of Glascow and his colleague Mike Burton believe they’ve solved the problem. They randomly gathered 20 images of 25 male celebrities on the Internet and fez fed the photos into a face recognition system that had a database of 31,000 photos of famous faces. The recognition system accurately identified the individuals about half of the time. The researchers then created what they called an average face of each celebrity, by taking his images in and averaging them out.

专家说面部自动识别系统，即电脑通过搜索上千张面部图片的数据库来识别一个人的技术正在得到广泛应用，但还不够可靠。系统不能识别不存在于数据库中的人，或数据库中的图片和站着电子眼前的人有明显区别。专家说这是由于保存的图片是很多年以前的，与这个人不太相似，或者姿势和灯光有不同。G大学的心理学家RJ和他的同事MB认为他们已经解决了这个问题。他们随机的从网上收集了25位名人的20张照片，放入拥有31000张名人照片的数据库中。识别系统精确的识别了其中一半的人。研究者还为收集了名人的照片总结出特点，从而建立了一个“面部模型”。


 总结
今天的录音很简单，错成这样实在是不应该。
