Abstract

Abstract:

A new watermarking algorithm based on fuzzy clustering and singular value decomposition is proposed. It makes good use of the HVS’s masking effect and searches the intricate texture field in the host image’s spatial field as the embedding position with FCM. Then the watermark is embedded based on SVD. Experimental results demonstrate that the proposed scheme effectively balances the conflict between the robustness and invisibility.

Key words: fuzzy clustering, HVS model, SVD, digital watermarking
