| Outline of Final Research Achievements |
We propose a new digital image watermarking method based on the dyadic wavelet packet transform (DYWPT) and fast interval arithmetic (IA) techniques. This method produces watermarked images that have better quality and are robust with respect to various types of attacks. We also propose a new image quality degradation assessment method based on the dual-tree complex discrete wavelet transform (DT-CDWT) for evaluating the image quality. Moreover, we propose a new computer-aided method for diagnosing early esophageal cancer from endoscopic images by using the dyadic wavelet transform and the fractal dimension, and a new detection method for early esophageal cancer from flexible spectral imaging color enhancement (FICE) mode based on the Daubechies wavelet transform.
