We describe and validate a computer-video system that records and displays in real-time the activity of multiple specimens in a user-defined space, at user-defined intervals. The computer program uses image subtraction algorithms to record changes in video images, and stores observations in column format or as a series of 2-D matrices. The program was tested under various lighting conditions, backgrounds, specimen size and specimen speed. An AV model of Macintosh computer with video input from a camera or video cassette recorder was used to record and analyze the mechanical movement of spots on a turntable and the locomotor activity of an ant colony. The limitations and potential applications of the program are discussed.
我们描述并验证了一种计算机视频系统，该系统能够按照用户定义的时间间隔，实时记录并显示用户定义空间内多个样本的活动情况。该计算机程序使用图像减法算法来记录视频图像中的变化，并以列格式或一系列二维矩阵的形式存储观测结果。该程序在各种光照条件、背景、样本大小和样本速度下进行了测试。使用一台带有来自摄像头或录像机视频输入的苹果麦金塔计算机的AV型号，来记录和分析转盘上斑点的机械运动以及蚁群的运动活动。本文还讨论了该程序的局限性和潜在应用。
