In a method of integrating one or more l-dimensional filters into a digital image stream interface a single digital video input is processed by multiple 1-dimensional digital image filters, especially recursive filters, and combined into a single digital image stream which can be transmitted via a high-speed interface to a host computer's memory such that each 1-dimensional filter output can be automatically extracted and placed into its own separate memory buffer for subsequent processing by a secondary image processing device. This additional processing can include the second pass of a two-pass separable filter implemented in software on a general-purpose CPU, and in particular can result in the generation of an image pyramid. This combined hardware and software approach can produce low-cost 2-D digital image filter implementations small enough to be added to existing standard ASIC's while still retaining high performance.

A compact image steering and focusing device has a generally rectangular frame containing at least one illuminator and at least one and preferably two cameras and a pan/tilt mirror on a tilting frame. There is a tilt axis through the frame. A tilt motor is attached to the frame to turn the frame about the tilt axis. Another camera is positioned in optical alignment with the pan/tilt mirror. The device can fit behind the cover plate of an automated teller machine. Images from the cameras on the titling frame are used to focus the other camera on one eye of the automated teller machine user to identify the user by iris analysis and comparison to an iris image or iris code on file.
