Abstract: System for determining authenticity of an object in which a light-source directs collimated or telecentric light toward an authentication-region on the object, which impinges on the authentication-region at a predetermined angle relative to the normal of a plane defined by the object, a portion of the light is reflected from the authentication-region and another portion of the light is scattered from the authentication-region, an imager, focused on the authentication-region, acquires a focused-image of the scattered-light, the image includes image-features related to surface-features-scattering-phenomena of the authentication region, the processor determines correspondence between part of the acquired image and a corresponding part of a stored-image corresponding to the authentication-region, the processor identifies the object as authentic when the acquired-image corresponds to the stored image, the processor identifies the object as non-authentic when the acquired-image does not corresponds the stored-image

Abstract: Apparatus for merging a video image sequence of a dynamic phenomenon occurring on a natural background into a high resolution background image, the apparatus including a background remover operative to remove the natural background from the video image sequence, and a phenomenon-background merger operative to merge the video image sequence of the dynamic phenomenon, with natural background removed, into the high resolution background image.
