FView - Extensible realtime image viewing, saving, and analysis app

The fview application makes use of motmot components to create a realtime camera viewer program that can record videos to disk. It includes a convenient plugin mechanism by which realtime video analysis can be performed. FView runs on Linux, Mac OS X, and Windows. This application is essentially a GUI frontend for cam_iface built using the wx toolkit. You may be interested in visiting the screenshot directory. It may optionally use our inexpensive, custom integrated Camera trigger device with precise timing and analog input. Here is a screenshot of fview running on Mac OS X using an iSight camera:

fview and flytrax screenshot

Here is another screenshot of fview and the flytrax realtime image analysis plugin. Note that the plugin is draws on the main display and to its own GUI window, which allows the user to interact with the online processing.

• flytrax is a realtime tracking system to track moving image features (a walking fly) using a simple but fast background-subtraction algorithm. Flytrax is freely available, open-source software distributed as part of the motmot package and functions as a plugin for fview.

ctrax - the Caltech Multiple Fly Tracker

• ctrax is multiple fly tracking software to enable quantitative analysis of fly behavior. From recorded videos, it tracks flies using a background/foreground model to track positions and orientations of individual flies over time. Identies of flies are maintained for long durations, with special care given to events such as close contact between flies and rapid movements. ctrax is free, open-source software.

trackem - Realtime multi-point tracker

• trackem tracks multiple bright or dark points and is used in our insect inspired flight control testbed

Flydra - Realtime multi-camera tracking of multiple flying animals

• Flydra is a realtime tracking system for performing marker-less tracking of moving image features, such as flying insects or birds. This multi-camera system uses, at its core, the motmot packages running simultaneously on multiple computers connected to multiple cameras to enable high spatial and temporal resolution in a large tracking volume with standard commercial components.
