• Abstract: We present SketchGPT, a flexible framework that employs a sequence-to-sequence autoregressive model for sketch generation, and completion, and an interpretation case study for sketch recognition. By mapping complex sketches into simplified sequences of abstract primitives, our approach significantly streamlines the input for autoregressive modeling. SketchGPT leverages the next token prediction objective strategy to understand sketch patterns, facilitating the creation and completion of drawings and also categorizing them accurately. This proposed sketch representation strategy aids in overcoming existing challenges of autoregressive modeling for continuous stroke data, enabling smoother model training and competitive performance. Our findings exhibit SketchGPT's capability to generate a diverse variety of drawings by adding both qualitative and quantitative comparisons with existing state-of-the-art, along with a comprehensive human evaluation study. The code and pretrained models will be released on our official GitHub.

  We propose a framework to control StyleGAN imagery with a single user sketch. We learn a conditional distribution in the latent space of a pre-trained StyleGAN model via energy-based learning. Our model can generate multi-modal images semantically aligned with the input sketch.

  Zero-shot sketch-based image retrieval typically asks for a trained model to be applied as is to unseen categories. We extend ZS-SBIR asking it to transfer to both categories and sketch distributions. Our key contribution is a test-time training paradigm that can adapt using just one sketch.

  We present B'ezierSketch, a novel generative model for fully vector sketches that are automatically scalable and high-resolution. We first introduce a novel inverse graphics approach to stroke embedding that trains an encoder to embed each stroke to its best fit B'ezier curve. This enables us to treat sketches as short sequences of paramaterized strokes and thus train a recurrent sketch generator with greater capacity for longer sketches.
