Additive type moire with computer image processing

Not Accessible

Your library or personal account may give you access

Abstract

Due to its poor visibility additive type moire is seldom used in spite of its simplicity. By means of computer image processing, the visibility of additive moire can be improved in real time to that of subtractive type moire. Experimental results for moire topography show that the additive type moire is no longer an inadequate method.
