Description: 当手指或笔触摸屏幕时，平常相互绝缘的两层导电层就在触摸
点位置有了一个接触，因其中一面导电层接通X轴方向的5V均匀电压场(图a)
，使得检测层的电压由零变为非零，控制器侦测到这个接通后，进行A/D转换
，并将得到的电压值与5V相比即可得触摸点的X轴坐标为（原点在靠近接地点
的那端）：Xi=Lx＊Vi / V（即分压原理）同理得出Y轴的坐标，这就是所有电
阻技术触摸屏共同的最基本原理。-finger or pen to touch the screen, usually two mutually insulated conductive layer on location in touch with a contact, because either side conductive layer connected to the X-axis 5 V voltage field uniformity (a map), measuring the voltage level from zero to nonzero, the controller connected to the detection of this now, A / D conversion, and the voltage V compared with the five it can touch points for the X axis coordinates (close to the original point of getting access locations) : Xi'an Lx = Vi * / V (ie pressure principle) come empathy Y axis coordinates, This is all technical resistance Touchscreen common basic principles.

Description: Detecting end points and junctions of lines is always problematic in matlab. This code enables to detect them in fast manner. Gives spatial coordinates of end points and junctions. Also gives information about number of lines connected in these junctions. The algorithm can be used in vessel detection, road detection, finger print recognition systems. Platform: |
