Video Tracking
WaterMaze’s analysis capabilities are unparalleled. Analyses can be viewed for single trials or exported for multiple trials directly to Excel. Scan through hundreds of trials easily with clickable animal and trial lists. Parameters include thigmotaxis, Moser’s zone, Whishaw’s corridor, Gallagher’s proximity, quadrant times and crossings and more. Suggestions for new analyses from our users are regularly incorporated. Swim paths can be exported to standard drawing programs. Movies of each trial can be stored and viewed through the WaterMaze Analysis windows or exported to PowerPoint and other presentation software. WaterMaze’s tracking is robust and easy to setup with standard CCD cameras and video boards. No special lighting or video-processing hardware is necessary. Utilizing a state-of-the-art image-processing software and videocapture card, images are acquired at up to 30 frames per second. The WaterMaze program identifies the animal whether it is lighter or darker than the background. A unique algorithm screens out changing shadows and changing lighting conditions that might occur during the trial. On-line interpolation identifies and smoothes occasional loss of signal that can occur if an animal swims briefly underwater or under hanging cue objects. A special set-up window can be used to measure the evenness of lighting across the pool surface, helping to eliminate deep shadows. The path is displayed in real time as the trial progresses. Landmarks or other cues of any color can be arranged in and around the pool, and the program can control multiple On-Demand (Atlantis) Platforms. Movies of each trial can be stored for later review or for export in QuickTime format to PowerPoint or other presentation software. At the end of each trial, the experimenter can type notes concerning the trial. The trial can be stopped manually or automatically when the animal reaches the platform or after a set interval. The program indicates the next animal, platform location and start position. Remote switches can be used to start, stop and save trials. Multiple switches for each function can be placed around the pool if desired. With the program in auto-sequence mode and autosave mode, multiple trials can be performed without a mouse or keyboard! WaterMaze goes far beyond existing programs in its ease of use and flexibility. Because it is designed in close consultation with users, WaterMaze is integrated seamlessly with the experiment.
