摘要：An improved scheme for contour detection with better performance measure has been proposed in thispaper. A 9x9 Laplacian and Gaussian (LOG) filter has been proposed. The present study has shown that the gradientimages obtained by the 9x9 LOG mask appears to be much clearer with sharp and prominent edges than those obtainedthrough 5x5 LOG filter. The method has been applied to a number of digital images and better performance measure ofcontour detection has been achieved.
