A Perimeter-Based Noise Filter Algorithm for Vehicle Recognition
Weihua Wang · 2009
Noise filter is the process of removing noise from a signal. In the area of image processing, the noise filter process is very important for the users. A new noise filter algorithm base on perimeter for vehicle recognition is proposed in this paper. Providing a edge detection methods based on Sobel operator, discussing the problem of noise in the boundary detected above, analysis the principle of the detailed solve approach for the problem, giving the implement of the algorithm. Experiments have been conducted by real vehicle images obtained from the real-time video produced by a monitor. The result shows that the new proposed method can remove the noise of the image signal for the vehicle recognition efficiently.
