1·Ray-casting algorithm is that ray passes volume cell of data field, sampling relative pels color to form video image.

光线投影算法将光线穿过数据场中的体元，采样得到相关象素的颜色， 形成可视图。

2·The spatial structure method is a classified method that is make use of relationships between pels and neighbour pelsis.

局部结构法是利用象元本身与周围象元之间的关系进行分类的一种方法。

3·Objective Based on a computerized color object segmentation technology, a novel ultrasonogram color flow pels quantitative analysis method is proposed.

目的提出一种新的基于计算机彩色目标分割技术的声像图彩色血流像素定量技术。

4·This arithmetic can capture the displacement of the fingerprint using the information contained in the pels of the sensor, it can also resume the fingerprint image without any crossover.

该算法巧妙地利用了有限个像素点的信息，能够有效地判断手指在扫刮方向上的位移在扫刮过程中的左右偏移，并能据此恢复出完整的没有任何交叠的指纹图像。
