WebAug 27, 2024 · Basic Overview Digital Watermarking (DWM) is a technique of protecting digital data. This code base implements 2 methods for marking digital images based on Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). WebThe watermark extraction algorithm: Divide the watermarked image into non-overlapping blocks of dimensions 8x8. Exclude the edge b_cut (50 in our example) pixels from the edges. Let’s assume we have n such blocks Let the value of key = k. This will be used as a seed for the pseudorandom generator.
