Hello Viewers, in this video, Watermarking of grayscale images using Discrete Wavelet Transform (DWT) is presented. The proposed watermarking scheme is based on spread spectrum watermarking, which is known to be robust against several attacks.
This video has following contents:
- What is image watermarking?
- Types of watermarking and challenges in image watermarking
- DWT based spread-spectrum watermarking for grayscale images.
- Watermark embedding and watermark extraction algorithms.
- Performance evaluation parameters.
- MATLAB Code to implement watermarking (Embedding/ Extraction).
- Result analysis.
