Abstract:  

 Abstract:  In order to overcome these defects such as sensitive to noise and prone to produce false edges for better extracting the car contour to significantly improve the accuracy, the extraction mechanism for vehicles contour based on Stransformation coupled Canny operator is proposed in this paper. The Stransformation is introduced into the Canny operator, and the intermediate frequency coefficient of Stransformation is used to extract contour. It significantly improves the ability of antinoise interference, and makes the Canny operator having the property of identifying the false edge information. This algorithm and other algorithms are tested by the Matlab simulation platform. And the results show that: comparing with the other extraction mechanism, the contour extraction accuracy of this mechanism is the highest, and the ability of anti noise interference is also the strongest for which its peak signal noise ratio up to 32.675.
