gVision
The gVision Camera Control Panel |
gVision is an image acquisition package designed for use in physiology research and education. gVision streams data from
several types of common live imaging devices to disk in a variety of supported formats (i.e. avi, fmf, tiff stack). gVision supports
several custom triggering modes that offer motion detection, time lapse photography, and pre-buffered event capture. gVision supports hardware
triggering of video frames (where supported by hardware).
gVision is an open source application allowing the user to customize the tool to acquire data and control other hardware as their expeirment
may demand. gVision custom trigger modes are designed to enable rapid experiment prototyping in Matlab for a broad variety of scientific and
educational applications.
Since gVision is a Matlab based application (compiled or otherwise), supported hardware includes that
supported by the Matlab Image Acquisition Toolbox.
- High end scientific imaging cameras
- i.e. Hamamatsu, QImaging, and Camera Link Cameras
- Intermediate range machine vision cameras
- i.e. Basler, Point Grey, AVT, etc
- Cheap streaming video cameras
- i.e. Webcams, streaming capture cards, etc

Camera Standards Supported by gVision
- DCAM compatible firewire cameras
- GigE Vision - GenICam Standard
- Camera Link
- Microsoft DirectShow compatible cameras
|
The development of gVision has continued under researcher driven feedback at the
HHMI Janelia Farm Research Campus in cutting edge neuroscience applications. The primary application of the tool are in
behavioral videography in model systems (i.e. fruit flies and rodents).
