The article discusses the characteristics of infrared background and small target in actual project application,an advanced max-median filter algorithm is proposed to improve SNR performance,and Robinson filter is used to suppresses background effectively.

Study on a method of removal ECG baseline drift based on median filtering;

The technology about echo edge detection and median filtering on radar image;

Classifying the stratums in the images from the geology radar sonde based on the BP neutral network and median filtering;

An effective adaptive median filter algorithm;

Denoising algorithm based on median filter and morphology;

The gray forecast model based on median filter and its application in dam deformation forecast;

There exist two (different) methods that can remove noiselinear filtering and medium filtering.

This paper modifies the traditional medium filtering algorithm,and provides a new algorithm which keeps the advantages of traditional algorithm and gets better results of dispel image noise by using iterative idea of synchronization renovating .

First,medium filtering is used to restrain the noise in an infrared image.

Image processing with medium value filter;

A practical method of removing image noise with medium value filter was put forward.
