What are “video analytics?”-DM368

Video analytics are functions typically used in video surveillance applications that automatically analyze live video streams to detect moments in time that are not based on a single image. They can be easily compared to an automated, artificial intelligence visual cortex of the brain – the part that assesses visual images.

State-of-the-art video analytics algorithms, or complex math functions made possible through a digital signal processor like DM368 in a video camera, to detect, track and map the positions of people, vehicles and other objects as they move and interact in the camera’s field of view. Video analytics are commonly used in video security applications for retail stores, community venues and transportation points. Video analytics can also be used in entertainment and health care applications.

How are video analytics possible on DaVinciTM digital media processors? The DaVinci digital media processors containing a digital signal processor (DSP), along with the video processing subsystem, enable complex algorithms and signal processing. These algorithms and signal processing functions are implemented via software programming on the DSP in the DaVinci digital media processors. To make this development easy, TI has an extensive vision library that contains various video analytics algorithms for developers to utilize as a starting point to save time when programming the DSP for their specific video analytics.

What are some examples of video analytics?

Motion detection is used to determine the presence of motion in an area being observed by a video camera or motion detector. Motion detection is a common feature in video security alarm systems.

Object detection determines the presence of people or objects being captured through video and relays what type of objects they are real-time. This type of video analytics on DM368 can include fire and smoke detection.

Face recognition can capture and possibly identify people, which is helpful for video airport security for terrorism or criminal detection. The same type of analytics can be used for automatic license plate recognition. Tamper detection enables an alarm to alert the proper entity when a camera or output signal has been compromised.

DM368 Tamper detection is a popular feature in video security systems for retail stores. Video tracking determines the location of people or objects captured in a video signal and locates them on an external reference grid to find them.

Leading PoE technology and design

Reduces PoE development costs: The DM368  evaluation board features two controllers with associated circuitry on a two-layer printed-circuit board (PCB), minimizing material and build costs that often occur when using multiple boards.

Easy to use, "plug and play" operation: The evaluation module is also offered in auto mode, eliminating the need for host control.

IEEE-compliant: The TPS23861 passes the University of New Hampshire's Interoperability Lab and SIFO's test suites.

Thermal design flexibility: The TPS23861 consumption does not exceed 400 mW in any operating condition. The external FET architecture allows the design engineer to select the FET that best meets size, cost, and efficiency requirements.

Enhanced reliability:  The four-point detection feature avoids system damage by preventing erroneous start-up.

For custom power management programmability and configuration, the TI Design's motherboard provides interfaces for two optional boards, the MSP-EXP430G2 LaunchPad™ and DM368 Interface Adapter, which are both available in the TI eStore.

Leading PoE technology and design  With state-of-the-art semiconductor products and extensive systems expertise, TI enables manufacturers to quickly deliver higher-performance PoE products to end-equipment designers. TI is a founding member of the PoETec Consortium and University of New Hampshire's PoE Consortium. TI has been instrumental in IEEE's 802.3bt task force to deliver a higher power PoE standard.
