Edge Enhancement Filter; Emboss Filter - Microtek ScanMaker IIG User Manual

Edge Enhancement filter

The Edge Enhancement filter gives greater contrast to edges.
The filters can do this because edges are usually areas in an
image where gray or color levels change abruptly.

Emboss filter

The Emboss filter makes a selection appear raised or stamped
by suppressing the color within the selection and then tracing
its edges with black.
