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