Comparison of Different Wavelets for Watermarking of Colored Images

Digital watermarking is very lucrative field over the years. Researchers have tried various techniques for watermarking images. In recent time, wavelet transforms has emerged as a popular technique for image compression and watermark applications. The wavelet transform has high de-correlation and energy compaction efficiency. This paper presents a comparative study of various wavelet techniques for watermarking and tests the results in terms of watermarked image quality, extracted watermark quality and its substance to JPEG 2000 compression.
