Control camera hardware to record videos from.

Single worms: 800ењ†00, 1200x1024 and faster frame rates.

Whole plate: 2500x2500 resolution (5 Megapixels).

Industrial machine vision cameras (CCD) work.Frame Rate: 5-10fps is adequate, faster for swimming.Contrast: dark solid worms on light background.Bend Angle: Bending angle at the midpoint.Wavelength: Period of the sine wave the best fits the.Amplitude: Amplitude of the sine wave that best fits.Moving Average Speed: Instantaneous speed.Instaneous speed: Velocity along the central axis from.Postion is the center of the median axis.Width is calculated from N points along the worm.Length: Distance between head and tail along central.Delete worms per frame or across all frames.Manually draw a worm that is not detected prior to.Head/tail identification can be swapped.The head moves more frequently than the.The wormвЂ™s tail area is thinner than the.The wormвЂ™s tail area is lighter than the head.The algorithm measures 2 points of high curvatureДЇrom a closed planar B-spline curve around the.The image is inverted and segmented to identify.Uses geometric model, worm motion model, backtrackingДЄnd Multiple Hypothesis Tracking for accurate detection.Thresholding tools to refine background and improveДetection despite moderate background clutter.Tracking (determining changes in worm position and shape from.Detection (finds new worms as the enter the movie).Supports high mag and low mag (whole plate) tracking.
