Dual-channel video analyzer controller

The controller is designed for two video-streams composition purposes: first stream is from CMOS sensor, the second is artificial computer-generated."Frame-by-frame" editing algorithm is embedded with ability to generate the resulting output stream with a different video resolution and standard. Silica (AVNET) debugging boards, Texas Instruments 6416 DSK and user-defined video input daughterboard are implemented in  the system.

High-speed Micron MT9M CMOS video-sensor with VGA resolution and a wide range of frame reading speed (15:90 frames per second) is used. Standard video-interfaces such as Component video, Composite video, S-video based on "front-end" interface chips from  Analog Devices have been applied. The user-defined image-filters for mixing, correlation, edge detection SAD calculation and ROI extraction as well as the "host-target" applications for communication with the workstation have been developed. High-speed interfaces USB 2.0 and 2xEthernet 10/100 are used for connectivity purposes.
