Feed-customized processing of multiple video streams in a pipeline architecture
First Claim
1. A method for analyzing video data that represents one or more video streams, the method comprising:
- providing an interface designed to allow, at a stage of a multiple stage pipeline, performing, by a first analyzer application and as first video data passes through the stage of the pipeline, a first set of analysis operations on the first video data to examine the content of the first video data, wherein the first video data is associated with a video stream from a first camera; and
performing, by a second analyzer application and as second video data passes through the stage of the pipeline, a second set of analysis operations on the second video data to examine the content of the second video data, wherein the second video data is associated with a video stream from a second camera.

Abstract
A pipeline architecture for analyzing multiple streams of video is embodied, in part, in a layer of application program interfaces (APIs) to each stage of processing. Buffer queuing is used between some stages, which helps moderate the load on the CPU(s). Through the layer of APIs, innumerable video analysis applications can access and analyze video data flowing through the pipeline, and can annotate portions of the video data (e.g., frames and groups of frames), based on the analyses performed, with information that describes the frame or group. These annotated frames and groups flow through the pipeline to subsequent stages of processing, at which increasingly complex analyses can be performed. At each stage, portions of the video data that are of little or no interest are removed from the video data. Ultimately, “events” are constructed and stored in a database, from which cross-event and historical analyses may be performed and associations with, and among, events may be made.

49. A system for analyzing video data that represents one or more video streams, the system comprising:
at a stage of a multiple stage pipeline, means for performing, by a first analyzer application and as first video data passes through the stage of the pipeline, a first set of analysis operations on the first video data to examine the content of the first video data, wherein the first video data is associated with a video stream from a first camera; and
means for performing, by a second analyzer application and as second video data passes through the stage of the pipeline, a second set of analysis operations on the second video data to examine the content of the second video data, wherein the second video data is associated with a video stream from a second camera.
