In watermarking, message is embedded in to another message. A stego message is formed after embedding a new message. In the implementation of the proposed system, 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. CaDEED-N&I exploited more by adopting the noise visibility function and proposing the importance factor (IF) for different watermark pixels. The performance of the proposed system can be measured with the help of PSNR, SSIM and CDR measurements, NTPSNR and CB-CDR.
