Compact intelligent surveillance system comprising intent recognition
First Claim
1. An intelligent imaging device comprisingA 360-degree view, fish-eye lens electronic imaging system for acquiring an image in a predetermined range of the electromagnetic spectrum from the interior of a vehicle through at least one vehicle window and for generating image data frames from the image,image processing means for receiving and processing the image data frames wherein the image processing means comprises an algorithm for generating a predetermined output when a predetermined data pattern is identified from the image data frames.

Abstract
An intelligent surveillance system is disclosed for the identification of suspicious behavior near the exterior of a vehicle. The system of the invention is comprised of a “fish-eye” visible camera imaging system installed on the interior ceiling of an automobile for the 360-degree imaging and observation of the lower hemisphere around the perimeter of the vehicle. The camera of the system is augmented with an embedded processor based on DSP (digital signal processor) or FPGA (field-programmable gate array) technology to provide for the automatic detection of suspicious/hostile activities around the vehicle. The system is preferably provided with wireless transmitter means for alerting a person (e.g. the owner) of detected suspicious behavior.

2. A method for identifying a predetermined human behavior comprising:
-
acquiring a first source image data frame and a second source image data frame, subtracting the first source image data frame from the second source image data frame to define a difference frame, binarizing the difference frame using a predetermined threshold value to generate at least one image blob, identifying motion saliency from a sequence of binarized difference frames by using a blob growing process. - View Dependent Claims (3, 4)
