Abstract: A method for tracking movement of nematode worms comprises: (i) providing a plurality of worms on a translucent substrate; (ii) obtaining a first image of a field of view including the plurality of worms by transmission imaging; (iii) obtaining a first difference image of the plurality of worms corresponding to an intensity difference between said first image and a background image of the field of view; (iv) repeating the following steps (a) to (d) a plurality of N times, for n=1 to N: (a) determining, from the first difference image, an nth pixel corresponding to a maximum intensity difference; (b) selecting, from the first difference image, an nth block of pixels comprising the selected nth pixel; (c) determining a coordinate associated with the selected nth block of pixels; and (d) updating said first difference image by setting each pixel of said nth block of pixels in said first difference image to a value corresponding to a zero or low intensity difference; (v) obtaining a sequence of M subsequent image

Abstract: A non-contact sensing system is provided for acquiring three-dimensional contour information of an object. The system is comprised of: a light source subsystem operable to scan a point of light in an area of illumination; a first imaging device having a field of view arranged to intersect with the illumination area and operable to capture image data; and a second imaging device having a field of view arranged to intersect with the illumination area and operable to capture image data. A first control module is in data communication with the first imaging device to determine contour information for an object in the field of view of the first imaging device and report the contour information for the object in a common coordinate system. A second control module is in data communication with the second imaging device to determine contour information for the object in the field of view of the second imaging device and report the contour information for the object in the common coordinate system.

Abstract: A sensor system and method for analyzing a feature in a sensing volume is provided. The system receives image data from a sensor, where the image data including peaks corresponding to the intersection of laser lines with the feature. The system generates a dynamic window based on the entropy of the peaks.
