Creative Vector Drawing Generation

Sketch is a powerful communication tool naturally embedded in humans, allowing the expression of complex ideas through relatively simple forms. Unlike raster images, which are dense grid-based representations captured by cameras or sensors, sketches should be treated as inherently different and abstract data structures. In this work, we explore and develop sketch-based generation frameworks in vector drawing formats that better emulate the human creative process.The motivation for this research is twofold: (i) to emphasise the intrinsic creativity of human sketches and the importance of strokes in creative vector drawing generation tasks, and (ii) to develop vector-based sketch generation models that enhance 2D and 3D digital workflows for both artists and non-experts. Our research consists of three main works: (i) <strong style="color:rgb(0, 0, 0);">SketchXAI&lt;/strong&gt; tries to explore creativity by reorganising the strokes of sketches with our proposed model, which introduces a novel framework where classification models are adapted to generate vector drawings, emphasising the importance of strokes in creative sketch generation tasks. (ii) <strong style="color:rgb(0, 0, 0);">SketchDreamer&lt;/strong&gt; extends this approach by introducing a text-driven framework for vector sketch generation. By integrating vision and language models into our framework, <em style="color:rgb(0, 0, 0);">SketchDreamer&lt;/em&gt;allows users to describe their creative ideation through text prompts and transforms the simple drawings into detailed vector drawings step by step. (iii) <strong style="color:rgb(0, 0, 0);">DreamWire&lt;/strong&gt;, which represents a significant leap into the 3D space, enabling the generation of multi-view wire art -- an intricate form of sculpture that reveals different interpretations when viewed from various angles.</strong></em></strong></strong>We look forward to our research culminate in a vision of future where AI plays a central role in expanding the possibilities of artistic expression, making sketch -- a complex and abstract form of art accessible to all.
