本算法是在经典Sobel算子基础上,结合汽车本身的实际情况,增加了6个方向模板,同时利用基于L2

范数的各同性扩散去噪模型消除噪声,最终得出汽车轮廓图。仿真结果表明:该算法对汽车图像的噪声干扰

有较强的抑制能力,汽车轮廓提取定位更准,精度更高,图像更清晰。-This algorithm is the classical Sobel operator on the basis of the actual situation with the car itself, an increase of 6 the direction of the template, while based on the L2

Norm homosexual diffusion denoising model to eliminate the noise, and ultimately come to the vehicle contour. Simulation results show that: the noise of the algorithm on the car image

Strong inhibition of the vehicle contour extraction positioning more accurate, more precise, clearer images.
