1.前言 众所周知,生物通过视觉来识别眼前物体的系统是相当出色的。比如,当一个习以为常的图象展现在眼前时,即使它局部有缺陷,或多少有些变形,人们仍能根据以前积蓄的经验等,准确地识别这一对象。 另外,根据生物所具有的这一非凡的视觉识别系统,人们利用现有的光学系统和电子线路等,在人工视觉方面所取得的成就,充分展示出构成高级识别处理系统的可能性。
1. Introduction It is a well-known fact that systems that visually recognize an object in sight are remarkable. For example, when a familiar image appears in front of us, even if it is partially flawed or somewhat distorted, one can still accurately identify the object based on previously accumulated experience. In addition, according to this extraordinary visual recognition system of living things, people’s achievements in artificial vision using existing optical systems and electronic circuits have fully demonstrated the possibility of constituting an advanced recognition processing system.
