【我的总结与翻译】

总结：sufficiently, randomly,

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 a database, are gaining in popularity, but are not very reliable.

专家表示，面部自动识别系统目前很流行，但它并不是很可靠。该系统中通过电脑存储在数据库中数千张照片来识别个人。

There won't be a match (if) the person's face is not contained in the database, or a match may be (overlooked if) a picture that is in the database looks (sufficiently) different than the individual standing in front of the system's electronic eye.

如果数据库内没有这个人的照片，那就找不到这个人的相关记录。或者，数据库中的图片与站在电子眼面前的人之间有很大区别，那么匹配就可能会被错过。

Experts say that's because the stored photograph may be several years old (and) bear little resemblence to the individual, or the pose or light may be different.

专家表示这是由于存储在数据库内的照片可能是几年前的旧照片，跟现在的模样一点也不像；可能与姿势和灯光不同也有关。

Psychologist Rob (Jenkins) of the University of (Glascow) and his colleague Mike (Burton) believe they' solved the problem.

Glascow大学的心理学家Rob Jenkins和他的同事Mike Burton则认为他们已经解决了这个问题。

They randomly gathered 20 images of 25 male celebrities on the Internet and fed the photos into a face recognition system that had a database of 31,000 photos of famous faces.

他们在互联网上从25名男性名人中随机收集了20张照片，并将这些照片输入到一个有31,000位名人照片的数据库中。

The recognition system accurately identified the individuals about half of the time.

该识别系统精确地识别出了其中一半的人。

The researchers then created what they call an "average face" of each celebrity by taking his images and averaging them out.

研究人员还为每个名人收集好几张照片并找出最普通的特征，从而建立他们所谓的“平均脸”系统。

其实今年说得蛮清楚的，但还听成了这样，居然两 if 都不对。。。。
