Discrete Wavelet Transform Based Optoelectronic Water Mark Technology
Journal Title: International journal of Emerging Trends in Science and Technology - Year 2017, Vol 4, Issue 2
Abstract
An Optoelectronic watermark technology plays a vital role in Authentication and in enhancement of invisible watermark code display or to extract the invisible watermark code from the object image. By using this technique the image can be watermarked and it can extract the higher resolution image. A flat-panel display is used to demonstrate the invisible data hidden behind the watermark codes embedded into the object image by use of the installer. The variation of the prototype for taking out the watermark codes is made by using viewer. The Discrete Wavelet Transform and Inverse Discrete Wavelet Transform (DWT/IDWT) scheme is used in 3-level watermarking. The 3-level DWT is used to display the invisible hidden watermark code and extract the image with better quality with limited execution time. The performance can be analyzed by the PSNR value and MSE value of the object image. Watermark technique is used to increase the Security, Robustness, Payload and Quality. This technology finds excessive application in Business and Industry
