摘要
有针对性地提出了遥感和地理信息系统(RS&GIS)课程的教学软件设计思想,并在实践上充分利用多媒体超媒体技术,实现软件系统的高起点。作为一个开端,为在21世纪实现全方位、立体化的崭新教学手段和方法进行了探索,以促进遥感地理信息系统这一技术工具的进一步推广。
In this paper the MMX TM technology recently developed by Intel is briefly introduced and an algorithm of edge extraction and crossing point extraction by using the MMX TM technology is presented. By taking advantage of technology supported by MMX TM the speed of edge extraction can be performed at the rate of 30 frames/s.
