System and method for analyzing video from non-static camera
First Claim
1. A system for analyzing images acquired from a single non-static camera when viewing an observed area, said system comprising:
- a memory;
a processor in communication with the memory, wherein the processor is configured to perform a method comprising;
generating, during a first pass of said non-static camera viewing an observed area under surveillance, a reference model from one or more image frames acquired from said camera;
acquiring current image frames during successive passes of said non-static camera viewing said observed area,applying, to current image frames feature based registration in conjunction with camera position, to determine a respective output image sequence of images, each image of said output image sequence corresponding to a respective reference image of said reference model; and
,storing, in a memory storage device, successive output images from said imaging device; and
,analyzing each of said successive output images for detecting a change in a desired feature of the observed area.

Abstract
A novel system and method of treating the output of moving cameras, in particular ones that enable the application of conventional “static camera” algorithms, e.g., to enable the continuous vigilance of computer surveillance technology to be applied to moving cameras that cover a wide area. According to the invention, a single camera is deployed to cover an area that might require many static cameras and a corresponding number of processing units. A novel system for processing the main video sufficiently enables long-term change detection, particularly the observation that a static object has been moved or has appeared, for instance detecting the parking and departure of vehicles in a parking lot, the arrival of trains in stations, delivery of goods, arrival and dispersal of people, or any other application.
