Presence/Absence Tools - Sharpness

The Sharpness Presence/Absence Tool determines whether or not an image is focused properly, based upon the image sharpness score within the region. The tool computes a measure of the relative focus of an input image, as part of iterative process for refocusing the lens of an In-Sight vision system.

The image sharpness score indicates the degree to which the region within the image includes the smallest resolvable features in a "scene" (i.e., the object and its background, as captured in the image).
