DWT has excellent frequency spread, spatial localization and multi-resolution characteristics. DCT offer compression while DWT offers scalability in watermarking. These techniques and properties are used in a combined DCT DWT watermarking technique.
Digital watermarking in MATLAB can be implemented using various techniques, including spatial domain and frequency domain methods. A simple approach involves embedding a watermark image into a host image by modifying pixel values or using Discrete Cosine Transform (DCT) for frequency-based watermarking. You can use MATLAB's built-in functions like imread, imshow, and matrix operations to manipulate images. For example, to embed a watermark, you can blend it with the host image and then extract it by analyzing the modified image.
