Abstract

A detector for low-contrast blemishes on objects with high foreground-background contrast is described. An edge detector is followed by logical shifting and expansion operations in order to locate occurrences of spatial proximity of the edge orientations and polarities expected. Maximum and minimum sizes of defect detected are adjustable.
