BézierSketch: A Generative Model for Scalable Vector Sketches

Abstract: The study of neural generative models of human sketches is a fascinating contemporary modeling problem due to the links between sketch image generation and the human drawing process. The landmark SketchRNN provided breakthrough by sequentially generating sketches as a sequence of waypoints. However this leads to low-resolution image generation, and failure to model long sketches. In this paper we present BézierSketch, a novel generative model for fully vector sketches that are automatically scalable and high-r… Show more

“…18, the noses in our results are connected with the eyebrows while they are clearly separated in those from Photo-Sketching. The non-smoothness problem could be addressed by using a curve refinement technique [Das et al 2020] as post-processing. In addition, the performances on both tasks could be improved by combining the pixel-level sketch simplification or image-to-sketch model and our approach in a single end-to-end model, which may be a promising future direction.…”

“…A number of works on learning with vector training data have been proposed in recent years, e.g., sketch reconstruction [Das et al 2020;Graves 2013;Ha and Eck 2018], and image-based drawing generation [Egiazarian et al 2020;Song et al 2018]. While, in general, it is more straightforward and easier to learn with direct vector supervision, it is not always feasible to collect vector training data.…”

“…Furthermore, even artificial sketch generators, when trained to create a sketch to convey the essence of an image with as few strokes as possible, learn to first draw lines that convey global structure and shape, prior to any details [ 34 ]. In fact, there have recently been a number of artificial neural networks trained to generate sketches that are as easily recognizable as those generated by a human [ 35 , 36 ]. We here show that drawings that take advantage of the visual system’s mechanisms for understanding scenes will be more easily interpreted [ 37 ].…”

“…Furthermore, even artificial sketch generators, when trained to create a sketch to convey the essence of an image with as few strokes as possible learn to first draw lines that have the most power to convey essential content [22]. In fact, there have recently been a number of artificial neural networks trained to generate sketches that are as easily recognizable as those generated by a human [23,24]. We here show that drawings that take advantage of the visual system's mechanisms for understanding scenes will be more easily interpreted [25].…”
