Developing Real-Time Computer Vision Applications for Intel Pentium III based Windows NT Workstations

In this paper, we describe our experiences in developing real-time computer vision applications for Intel Pentium III based Windows NT workstations. Specifically, we discuss how to optimize your code, efficiently utilize memory and the file system, utilize multiple CPUs, get video input, and benchmark your code. Intrinsic soft real-time features of Windows NT are discussed, as well as hard real-time extensions. An optimized real-time optical flow application is given. Empirical results of memory subsystems and cache scheduling issues are also reported.
