Research ArticleOpen accessComparison and Analysis of Discrete Cosine Transform based Joint Photographic Experts Group Image Compression using Robust Watermarking AlgorithmS.M. Ramesh, Dr. A. ShanmugamProblem statement: The performance of the watermarking algorithms is analyzed using different compression standards to study the watermark extraction behavior of these algorithms. Approach: A digital watermarking method is said to be effective if the watermark embedded in an image by it could survive against diverse attacks ranging from compression, filtering to cropping. Several techniques are presented in the literature … …American Journal of Applied Sciences, Vol. 8, Issue 1 · 31 Jan 2011 · 7,680 accessesView PDFCite
