A Novel Approach on DWT Province for Colorant Watermarking
Journal Title: International Journal of Electronics Communication and Computer Technology - Year 2014, Vol 4, Issue 5
Abstract
This article aims at lightweight, visionless recognition of additive spread-spectrum watermarks in the DWT domain. We focus on two host signal clatter models and two types of postulate tests for watermark recognition. As a crucial point of our work we take a closer look at the computational necessities of watermark sensors. This involves the computation of the uncovering response, stricture estimate and porch selection. We show that by switching to estimated host signal parameter approximations or even stable parameter settings we attain an astonishing enlargement in runtime performance without surrendering recognition enactment. Our tentative results on a large number of images confirm the assumption that there is not necessarily a trade-off between calculation time and exposure concert.
