视觉原理及图象数字化表达

Vision Principle and Image Digitizing

建立了简单的视觉模型,确定了物体表面的几何形状、光源的投射方向和强度、物体表面的反射特性等与灰度分布间的关系,描述了数字图象采集、量化及其基本表示方法.

A simple vision model used in computer vision analysis is presented in this paper. The relationship between the image gray level and geometric shape and reflectance of the object, the projecting direction and intensity of light source are also theoretically analyzed, with the image digitizing principles and image format described as well.
