We present a sketch-based image editing technique that allows users to modify an image using a set of strokes drawn on the image. The proposed approach uses clothoid curves to beautify the sketched deformation curves. A deformation diffusion algorithm then spatially distributes the user specified deformations through out the image to produce smooth transformations from the original image to the resulting image. We demonstrate the technique on a variety of image types including photo-realistic images, real product images, and sketches.
