A Study on Edge Tracing for Vehicle Algorithm

Feature extraction is an important step for vehicle recognition. However, there are many regions in a vehicle image, and it is difficult to extract the edge vectors of the regions of the image. So, a new developed contour tracing approach has been proposed in this study, it was applied to the pixel set formed from the vehicle image in order to obtain the characteristic vector which is very important in the vehicle recognition. This approach is based on scan-line and neighborhoods of the analyzed point algorithm. The results of this test shows good sensitivity to noise and local edge distortions, it also shows that the edges of basic non-convex and convex objects could be determined easily.
