Video analytics systems and methods are described that typically comprise a video encoder operable to generate macroblock video analytics metadata (VAMD) from a video frame. Functional modules receive the VAMD and an encoded version of the video frame is configured to generate video analytics information related to the frame using the VAMD and the encoded video frame. The downstream decoder can use the VAMD to obtain a global motion vector related to the frame, detect and track motion of an object within the frame and monitor a line provided or found within the frame. Traversals of the line by a moving object can be detected and counted using information in the VAMD and the line may be part of a polygon that delineates an area to be monitored within the encoded frame. The VAMD can comprise macroblock level and video frame level information.
A video analytics system comprising a video encoder operable to generate macroblock video analytics metadata (VAMD) related to a video frame while the video encoder is compressing the frame, wherein a compressed version of the video frame and the VAMD are concurrently transmitted to one or more decoders modules operative to generate video analytics information related to the video frame using the VAMD and a decompressed version of the video frame.
A video analytics method, comprising:
A non-transitory computer-readable medium encoded with data and instructions wherein the data and instructions, when executed by a processor of a video decoder system, cause the video decoder system to perform a method comprising:
