The techniques of object detection and tracking are the focal points in the fileds of computer vision.There are some drawbacks in the traditional methods of moving object detection and tracking

such as easily disturbed by noise and trembling.Aming at these problems

this thesis proposes a method which uses the algorithms of Independent Component Analysis(ICA) in the segment of target extraction and image denoising.The goal is to improve the robustness of detecting and the accuracy of denoising so that we can...
