Content analysis in security, surveillance apps

Keywords:Video content analysis  analytics 

The transition from analogue to digital video is bringing long-awaited benefits to security systems, largely because digital compression allows more image data to be transmitted and stored. Video content analysis (VCA), also known as video analytics, electronically recognises the significant features within a series of frames and allows systems to issue alerts when specific types of events occur, speeding real-time security response.

Adaptive methods of separating foreground objects from the background, then tracking objects and, if necessary, classifying suspicious activities are all aspects of VCA that require a high level of real-time processing computation and adaptability. DSP-based video processors offer the performance needed for VCA and video encoding, plus programming flexibility that canadapt to changes in application requirements and techniques, thus raising video security to anew level.
