我们提出了一个软件（ETHOWATCHER (R)）开发，以支持人种志，目标跟踪和从实验动物的数字视频文件中提取运动学变量。跟踪模块可以从背景中有控制地分割目标，提取图像属性，用于计算实验动物的行进距离、方向、长度、面积和路径图。地理记录模块允许从环境或视频文件连续或逐帧记录基于目录的行为。输出以用户设置的时间分段格式报告每个行为的持续时间、频率和延迟以及事件的顺序。对运动学测量和对已知药物行为影响的检测进行了验证测试。该软件可在www.ethowatcher.ufsc.br免费获得。(C) 2011 Elsevier Ltd.版权所有。
We present a software (ETHOWATCHER (R)) developed to support ethography, object tracking and extraction of kinematic variables from digital video files of laboratory animals. The tracking module allows controlled segmentation of the target from the background, extracting image attributes used to calculate the distance traveled, orientation, length, area and a path graph of the experimental animal. The ethography module allows recording of catalog-based behaviors from environment or from video files continuously or frame-by-frame. The output reports duration, frequency and latency of each behavior and the sequence of events in a time-segmented format, set by the user. Validation tests were conducted on kinematic measurements and on the detection of known behavioral effects of drugs. This software is freely available at www.ethowatcher.ufsc.br.
