Abstract :
A new grey scale image representation using a binary sketch image is presented. The sketch algorithm consists of three steps: preprocessing by wavelet denoising, convolving with a Laplacian operator and thresholding. It is shown that the sketch image provides an alternative and visually better representation of the original image than the edges
