Image Watermarking using Wavelet Transforms ECE Project
This is a good Electronic and communication project on "image watermarking using wavelet transforms". Image watermarking is the process of embedding a secret message, watermark, inside an image such that the visual perception of the watermarked image is unaltered and the watermark is invisible and robust to attacks. This secret watermark is used for copyright protection and ownership authentication. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.
The proposed method uses the concept of image hard thresholding to determine which coefficients not to embed the watermark into. This involves finding the threshold for hard denoising and keeping all the coefficients under this threshold unmodified and choosing the coefficients just above the threshold to embed the watermark.
