Moving objects detection is a fundamental step in many vision based applications. Background subtraction is the typical method. Many background models have been introduced to deal with different problems. The method based on mixture of Gaussians is a good balance between accuracy and complexity, and is used frequently by many researchers. But it still cannot provide satisfied results in some cases...
Significant brightness deviations between different camera views can often be observed in multi-view images. In this paper, a new method of brightness correction based on dynamic programming with control points constraint is proposed. The SIFT feature is firstly extracted and matched. The fundamental matrix constrain is then applied with RANSAC algorithm, and the inliners of matched points are acquired...
This paper proposed a new method for infrared people-counting. According to the characteristics of the time continuous data collected by infrared sensors, the pattern recognition idea is introduced in the data processing procedure. After the special pretreatment, adaptive segmentation and feature extraction for the people-counting data, the feature vector is used as the inputs of the trained support...

As a Country with big stored-coal, the development of Integrated gasification combined cycle (IGCC) will largely increase the efficiency in the power plant and decrease the environmental pollution from the power plant; and the Research and Development of hot gas sulfur removal sorbent is one of the key technologies of IGCC. The most difficult controlled problem in the hot gas desulfurization in IGCC...
Blocking artifacts are significant problem in DCT-based image compression, which introduce the apparent distortion of visual quality. In this paper, an effective blocking artifacts deduction method is proposed.Compared with other existed method, firstly, fast edges map identification was done in compressed data. Secondly, an adaptive criterion of block type is introduced according to DCT coefficients...
