Abstract:

A new horizontal template and vertical template algorithm is proposed in view of the algorithm complexity and programming difficulty using Laplacian operator and gradient operator extracting image edge.By simulation experiment,the image edge is extracted which is better than the edge image using gradient operator extraction.By improving the algorithm,the time of Image Edge Extraction is reduced with little image Information missing.The algorithm provides valuable reference for further research into the locating and matching of image.
