An artist usually does not draw all the areas in a picture homogeneously, but tries to make the work more expressive by emphasizing what is important while eliminating irrelevant details. We present a technique for automatically converting an input image into a pencil drawing with such effect of emphasis and elimination [HATA, et al. 2012]. The technique combines Saliency Map [ITTI, et al. 1998] and Line Integral Convolution(LIC) based pencil drawing filter [MAO, et al. 2001]. Saliency map is used to predict the focus of attention in the input image. Multi-resolution pyramid is used to locally adapt the density and appearance of pencil strokes to the degree of attention defined with saliency map
