A new encryption technique is proposed to encrypt color images using existing optical encryption systems for gray-scale images. The color images are con¨erted to their indexed image formats before they are encoded. At the decryption end, the color images are reco¨ered by con¨erting the decrypted ind

We investigate frequency conversion of near-infrared laser sources to generate visible laser outputs with segmented quasi-phase-matching (QPM) gratings through second-harmonic generation process. Analysis shows that segmented gratings have much broader conversion bandwidth and environment temperatur
Modeling object shapes from multiple range images requires three processes: correction of measurement errors, registration of data shapes, and integrating them as a unified shape representation. We propose a method by which these tasks can be solved simultaneously. Discrete samples of the signed dis
