The proposed filter calculated the noise rate of the corrupted image based on the minimum local entropy, and utilized the noise rate to determine the size of filter windows and the number of pixels to be brushed off in the filter windows of Alpha-trimmed mean filter, and then used the average of leaved pixels gray as the output of the filter.

Optimal size of the sliding window in flow control;

Based on the sliding window of the counting vehicle and location forecast;

Optimal algorithm of data streams clustering on sliding window model;

Research of sliding windows scheme based on data stream;

Also, the sliding windows time estimator is employed to reduce the influence of random noise synchronization.

A novel mechanism called the exemplary sketch was proposed to evaluate Max and Min over sliding windows with various sizes in the real time data stream environment.

As for the software design,three-stage algorithm was used,and a new instantaneous protection algorithm based on the three-dot slip window and the improved differential coefficient method was .

This paper presents a new compositive VAD algorithm base on one kind of slip window.

In accordance with theory of flow control, this paper discusses flow control model based on slip window technology, and analyzes and studies the model with the help of statistics.
