| Abstract: | With wide use of digital image compression code technology, the people demand the real-time nature of compression code technology. How to realize rapid and effective image compression code has to be settled urgently This article analyzes the lifting algorithm and integer wavelet transform based on the lifting algorithm, and proposes a new digital image code method based on integer wavelet transform and tree characteristic flat surface. This scheme accomplishes code process by one time scanning of the wavelet modulus. So it is easy in implementation and is of high performance, and could greatly, save processing time as compared with zero tree encoding. |
