• Jun 4, 2026 dwt based watermarking algorithm using haar wavelet ortion. Algorithmic Workflow The DWT-based Haar wavelet watermarking algorithm generally follows a sequence of steps: 1. Preprocessing Convert the host image to grayscale or process color channels separately. Normalize or standardize image data if necessary. 2. DWT Decomposition Apply single or mult By Roberta Herman
