In this paper, minimization of total variation has been proposed via level set equation and average curvature flow has been substituted with Min/Max curvature flow.

A novel Snake model for image segmentation is given based on minimal total deviation and region information.

On the basis of minimizing total mean square error (TMSE) and the steepest descent principle,by modifying the gradient of TMSE,a robust total least mean square (RTLMS) adaptive filter algorithm is proposed.

Controller performance assessment method of minimum variance based on adaptive filter;

Inverse design approach for minimum variance observers;

It only needs routine closed-loop operating data and knowledge of the process time delay using minimum variance as a benchmark in controller performance assessment.

In the paper,it has been discussed that the approach of determining weights considering the expert s level with geometric mean and least-square for multi-objective group hierarchical decision making,the example is given.

The quantitative synthetical appraisement model combined weighted setting value statistic and attribute mathematics and least-square etc.

The track initiation of multi-target in dense noisy environment is concerned A method combined improved Hough transform and least-square criterion is proposed.
