4 Best Paper SIGGRAPH involves identifying the fundamental visual properties of an object or scene. At the heart of sketching, artists must decide on the essential features to include in simple and minimal line drawings. “ You can’t offer a computational method for image-to-sketch translation and ignore abstraction and this main idea of different levels of abstraction, ” Yael tells us. “ If I ask you to draw a cat, you will draw it differently than me, an artist, or someone else. There is no single solution we can learn for sketches; rather, there are many correct solutions. ” Yael Vinker is a PhD computer science student at Tel Aviv University, under the supervision of Daniel Cohen-Or and Arik Shamir, with a particular interest in the intersection of art and technology. Yael’s work, proposing a new method for converting images into sketches, scooped a Best Paper award at SIGGRAPH 2022, and she is here to tell us all about it. While many papers have explored image-to-sketch translation , Yael’s work stands out as it recognizes the importance of abstraction and the concept of multiple levels of abstraction . Abstraction in art CLIPASSO: SEMANTICALLY AWARE OBJECT SKETCHING “The Bull” by Picasso - this is a good example of progressive abstraction, this also emphasizes that this task is not trivial, even for artists, it’s hard to make the right choices such that the abstract object remains recognizable and also visually appealing.
