In this work, we aimed to further improve the commonly used DCTDWT based watermarking method by combining the DCT-DWT with the FABEMD method. Rather than embedding the watermark in the whole image, in our approach, the image is decomposed using FABEMD method into a series of BIMFs and residue, while the watermark takes place into one of BIMFs. The experiments indicate that our developed FABEMD-DCT-DWT technique can achieve high imperceptibility while showing good robustness. Furthermore, the proposed method is compared with the DCT-DWT based method, and the experiment results confirm that the proposed method shows better performances.
