Outline of Final Research Achievements

We proposed an N-tree discrete wavelet transform. We implemented the transform and its inversion algorithm with many types of wavelet functions such as biorthogonal wavelets. We designed a preprocessor and a postprocessor of the transform. Using the advantages of N times redundancy, we applied it to digital watermarking to sounds or images. We showed that the transform can be used to solve blind source separation problems of sounds or images. We proposed ideas to estimate the rotation angles of some original image from mixtures of rotated and translated original images.
