Abstract
Basically in watermarking, a message is embedded into another message. After embedding a new message is generated that is called as a stego message. In this work, we expect watermark decoding performance with specific content of the cover video and watermark, different noise tolerance abilities of various cover video content. This paper proposes CaDEED with expectation constraint (CaDEED-EC) and CaDEED-NVF&IF (CaDEED-N&I). CaDEED-EC considered the expected performances only. CaDEED-N&I exploited more by adopting the noise visibility function and proposing the importance factor (IF) for different watermark pixels. In the experiments, the validation tests for CaDEED-EC and CaDEED-N&I are proposed. The selection of optimal local region sizes for CaDEED-N&I is proposed. The performances can be measured by PSNR, SSIM, CDR measurements, NTPSNR and CB-CDR.
