This paper, based on the analysis of the cell′s image, overcomes the shortcomings of the conventional background segmentation method and puts forward a new method for the cell′s background segmentation that uses the threshold camber.

Several kinds of gray scale reconstruction arithmetic to realize image background segmentation is synthetically utilized.

Background subtraction with human motion monocular images is the first step of human motion analysis.

In the modern war,detection of the small target in the condition of complicated background is an urgent problem for infrared control and guide,it is also the key of improving weapon system capability.

This paper put forward a new method for vehicle plate location in complicated background, which well compromised both the accuracy and speediness by making use of the gray-level characteristics of characters and background on vehicle plate and its 2-D distribution regulation, sampling the key pixel, plotting grid and locating operation twice.

Aiming at the detection of the weak and point targets in complicated background a detection algorithm that is based on the operation of morphological filtering and frame-to-frame difference is proposed.
