The high-frequency sub-bands perfect successive approximation quantization process using multiple scan threshold structured,and the image segmentation algorithm is used to the important sub-bands.

The well known embedded zerotree wavelet(EZW)coder uses successive approximation quantization(SAQ)process and zerotree structure of wavelet coefficients.

In order to eliminate systemic error caused by different times, different labs, different analysis methods, and to solve some problems in merging maps, we propose a map adjustment theory and gradual approach method, based on a hypothesis that there are same means and standard deviate of data in adjacent small areas between maps.

By means of constructional iterative equationthis paper presents a way to give out the existence and singularity of a type of e- quational root with gradual approach method.

Kepler s equations can be solved with the gradual approach, which can be further extended to the solution of the non-linear equations.
