Abstract: An iris recognition system and method generates a one-dimensional iris signature that is translation, rotation, illumination and scale invariant. It allows users to enroll poor quality iris images that would be rejected by conventional methods. In addition, the system and method generates a list of possible matches instead of only the best match. In this way, the users could potentially identify the iris image by deeper analysis (such as using traditional iris recognition algorithm for more accurate iris identification). Further, the system and method permits more toleration of noise (such as glare introduced by contact lens or eye glasses). Finally, the system and method improves iris identification process computational efficiency. The system stores a one-dimensional signature as opposed to the conventional two-dimensional image.

Abstract: Briefly, the present invention is a paint tray assembly comprising a multi-use paint tray having a trough located therein and at least one removable paint containers retained in a lateral fit within the trough of the paint tray with the removable paint container being separately removable from the trough of the paint tray to allow for individual emptying of paint compartments in the paint tray.

Abstract: A method and apparatus for spatter painting wherein an open-loop paint applicator which can be a paint roller cover having a set of elongated interconnected members or fibers that are rolled in a shallow layer of paint, preferably a thixotropic paint, to randomly draw paint from the paint reservoirs onto peripheral portions of the open-loop members that extend into the paint reservoir to produce a partially loaded paint roller cover having randomly spaced globules and droplets of paint thereon. When the partially loaded paint roller cover is rolled over a surface the paint globules and droplets located in a random pattern on the paint roller cover are transferred to a surface to produce a “spatter effect” even though the paint roller cover normally produces a textured surface.
