SVGDreamer: Text Guided SVG Generation with Diffusion Model

This repository contains the official implementation of our CVPR 2024 paper, "SVGDreamer: Text-Guided SVG Generation with Diffusion Model." The method leverages a diffusion-based approach to produce high-quality SVGs guided by text prompts.

🆕 Update

• [11/2024] 🔥 We released the SVGDreamer++, offering stronger visual representation and improved editing capabilities.
• [03/2024] 🔥 We released the code for SVGDreamer.
• [02/2024] 🎉 SVGDreamer accepted by CVPR2024. 🎉
• [12/2023] 🔥 We released the SVGDreamer Paper. SVGDreamer is a novel text-guided vector graphics synthesis method. This method considers both the editing of vector graphics and the quality of the synthesis.

Installation

1. Install Environment

You can follow the steps below to quickly get up and running with SVGDreamer. These steps will let you run quick inference locally.

In the top level directory run,

sh script/install.sh

or using docker,

docker run --name svgdreamer --gpus all -it --ipc=host ximingxing/svgrender:v1 /bin/bash

2. Download Pretrained Stable Diffusion Model

Downloading pretrained SD models by setting diffuser.download=True in /conf/config.yaml the first time you run it. (Alternatively, you can append diffuser.download=True to the end of the script.)

Or you can still download it manually,

• Model Link: https://huggingface.co/stabilityai/stable-diffusion-2-1-base
• Default model is stored in the /home/user/.cache/huggingface/hub/models--stabilityai--stable-diffusion-2-1-base

🔥 Quickstart: synthesize 6 SVGs at once

SIVE + VPSD

Prompt: an image of Batman. full body action pose, complete detailed body, white background, high quality, 4K, ultra realistic
Preview:

Particle 1	Particle 2	Particle 3	Particle 4	Particle 5	Particle 6
init p1	init p2	init p3	init p4	init p5	init p6
final p1	final p2	final p3	final p4	final p5	final p6

Script:

python svgdreamer.py x=iconography skip_sive=False "prompt='an image of Batman. full body action pose, complete detailed body. white background. empty background, high quality, 4K, ultra realistic'" token_ind=4 x.vpsd.t_schedule='randint' result_path='./logs/batman' multirun=True

• x=iconography(str): style configs
• skip_sive(bool): enable the SIVE stage
• token_ind(int): the index of text prompt, from 1
• result_path(str): the path to save the result
• multirun(bool): run the script multiple times with different random seeds
• mv(bool): save the intermediate results of the run and record the video (This increases the run time)

More parameters in ./conf/x/style.yaml, you can modify these parameters from the command line. For example, append x.vpsd.n_particle=4 to the end of the script.

SIVE

Prompt: an astronaut walking across a desert, planet mars in the background, floating beside planets, space art

🔑 Tips

• I highly recommend turning on xformer enable_xformers=True to speed up optimization.
• x.vpsd.t_schedule greatly affects the style of the result. Please try more.
• neg_prompt negative prompts affect the quality of the results
• By setting state.mprec='fp16', you can significantly reduce GPU memory usage.

📋 TODO

• Release the code.
• Add docker image.
• Support fp16 optimization.
