Filed:

Jan 17, 1997
Appl. No.:

8/783925

Edwin R. Olear - Hamlin NY
Assignee:

Eastman Kodak Company - Rochester NY
International Classification:

G01B 734
US Classification:

73105
Abstract:

A method of characterizing the roughness of a surface comprises counting peaks on a surface using a sensor by locating direction changes above a minimum and searches for the next direction change and where three changes are found of a valley, peak and another valley, one peak is counted. A signal qualifies as a peak if its short leg is above the normal threshold.
