 🌟 New Research Alert - CVPR 2024! 🌟
 📄 Title: "SVGDreamer: Text-Guided SVG Generation with Diffusion Model"
-📝 Description: Animatable Gaussians - a novel method for creating lifelike human avatars from RGB videos, utilizing 2D CNNs and 3D Gaussian splatting to capture pose-dependent garment details and dynamic appearances with high fidelity.
+📝 TL;DR: Given a text prompt, SVGDreamer can generate editable and versatile high-fidelity vector graphics.
+📝 Description: In this work, the author has introduced SVGDreamer, an innovative model for text-guided vector graphics synthesis. SVGDreamer incorporates two crucial technical designs: semantic-driven image vectorization (SIVE) and vectorized particle-based score distillation (VPSD), which empower our model to generate vector graphics with high editability, superior visual quality, and notable diversity.
