The system has been developed to implement data cleaning techniques .If the data in the data bases are incomplete, noisy and inconsistent and we wish to analyze data by data mining techniques, then we have to preprocess the data by using preprocessin

采用了Harrtraining和离子滤波算法实现了拥挤人群人头计数，非常有用。VC++和Opencv开发，采用Oepncv中的Harrtraining训练一个分类器即可运行-Human detection and tracking in high density crowds is an unsolved problem. Standard preprocessing techniques such as background modeling fail when most of the

Logarithm transform is the preprocessing techniques used to normalize the illumination variation. In the log domain the re ectance and illumination of the image can be easily
