de for intra prediction serves as a crucial foundation for researchers and engineers working in video compression and image processing domains. Intra prediction, a technique primarily used in video codecs like H.264/AVC and HEVC, aims to reduce spatial redundancy within a v
entered (mean removed) and whitened (decorrelated with unit variance). Whitening reduces the dimensionality and makes the sources more statistically independent. MATLAB’s `fastica` function usually handles whitening internally, but you can also perform
Divide the image into blocks (commonly 8x8 pixels). Apply DCT to each block. Modify specific DCT coefficients to encode the watermark. Apply inverse DCT to reconstruct the watermarked image. Extraction Process Overview To retrieve the watermark: Divide the watermarked image into blocks. Apply
