Abstract: Systems and methods are provided for constructing a composite image having an extended depth of focus from a plurality of spatially congruent source images of lesser depth of focus. The systems and methods are relatively fast, preserve detail, provide robust results on a variety of unpredictable workpiece features and configurations, and tend to suppress or reduce out-of-focus artifacts. The composite image is constructed by edge and/or boundary analysis to identify well-focused edges or boundaries in the source images. Each particular edge or boundary in the composite image is determined based on the source image containing the best-focused instance of each particular edge or boundary. The composite image is constructed outside of the previously constructed portions by surface analysis to identify well-focused surfaces in the source images, Each particular surface portion in the composite image is determined based on the source image with the best-focused instance of each particular surface portion.

Abstract: A delivery system comprising a first container (24) in which a first material is to be held; a second container (66) in which a second material is to be held, the second container being capable of being put into fluid communication with the first container to enable the second material to be added to the first material to form a flowable composition in the first container, and user-actuable means (72) for mechanically generating a pressure differential to allow all of the flowable composition which is discharged to be discharged from the first container (24) at any orientation.
