Abstract (en)
[origin: WO8300972A1] Image analysing method and system, and in particular method and system for analysing X-ray radioscopic images of the contents of an article of mail to detect the presence of Improvised Explosive Devices (IED's). The system comprises a CCTV camera to scan said image and provide signals indicative of the intensity of the image at any particular point, means to process said signals and provide an indication of when the signal makes a transition through a predetermined threshold level and also the duration of any signal whose threshold varies from the, or each, said predetermined level as a measure of the extent of dark or light areas on the image, and means automatically activated in response thereto for processing said signals to apply a pattern recognition technique and including a Transition Position Encoder, a High Speed RAM Buffer Circuit, a Direct Memory Access Circuit (DMA) all incorporated with a Single Board Computer (SBC).
