A novel unstable resonator configuration with a special designed self-filteringAperture, loaded with Nd:YAG, was used for generating passively mode-locked picosecondPulses.

An improved bootstrap filtering algorithm based on random sampling, which adapts quite well to the nonlinear/non Gaussian problems, was adopted to avoid "basic structure distortion" caused by conventional filtering algorithm and to increase the estimation precision of the total filtering algorithm.

The results show that after human body image filter by self-adaptive filtering, not only the filter effect is better than the traditional filtering, but also prefects the human body image's edge information.
