Abstract: This paper puts forward a novel method for wavelet transform by dividing the source image into different layers based on intensity layers.The color image is converted to a gray image，and different direction images are generated with wavelet decomposition.The four images is made reconstruction，for three high-frequency layers add Gaussian noise，and the motion blur is applied for all layers，it can achieve different texture direction.It applies neon processing，negative and gradation with a color image to generate shape in pencil sketching.It adds all layers with texture direction and contour together to obtain the final pencil sketch.The experimental result shows that，compared with existing algorithms，the approach can change the input image into colored pencil drawing more fast，and the result is satisfactory.
