Blue light has been shown to elicit a tumbling response in Escherichia coli, a nonphototrophic bacterium. The exact mechanism of this phototactic response is still unknown. Here, we quantify phototaxis in E. coli by analyzing single-cell trajectories in populations of free-swimming bacteria before and after light exposure. Bacterial strains expressing only one type of chemoreceptor reveal that ...

data is a point cloud: a collection of points in three dimensional space, where each point can have additional features associated with it. With an RGB-D sensor, the color can be one such feature. Additionally, approximated surface normals are also often stored with each point in a point cloud. 1.2. Devices

Later in this chapter, in Supercharging the GS3-U3-23S6M-C and other Point Grey Research cameras, we cover a nuanced example of integrating OpenCV with other libraries, specifically FlyCapture2 for capture and SDL2 for display. PS3EYEDriver comes with a comparable sample, in which the pointer to captured data is passed to SDL2 for display.
OpenCV usually makes it incredibly easy to open a camera and start processing frames, but unfortunately when it doesn't work it's not clear how to debug. I found python wrappers for libusb and libdc1394 and included them in my code, which resulted in no errors, but no luck grabbing frames either.

Captured images are relayed to the main control PC via Ethernet using the GigE video communication protocol. On the control PC, the Point Grey FlyCapture SDK was used to acquire the incoming images from the GigE stream. For additional image post-processing, an OpenCV, an open-source toolkit for image processing and machine vision is used.
an interface for Flir (previously Point Grey) cameras is provided through the vpFlyCaptureGrabber class, a wrapper over FlyCapture SDK. It allows to grab images from any PointGrey USB-2.0, USB-3.0, GiGE, or firewire camera under Linux and Windows. This driver is known to work with Point Grey Flea3 USB 3.0, Flea2 and Dragonfly2 firewire cameras.

Gaze tracking is the technology that identifies a region in space that a user is looking at. Most previous non-wearable gaze tracking systems use a near-infrared (NIR) light camera with an NIR illuminator. Based on the kind of camera lens used, the viewing angle and depth-of-field (DOF) of a gaze tracking camera can be different, which affects the performance of the gaze tracking system ...
