SVGDreamer: Text Guided SVG Generation with Diffusion Model

cvpr24 arXiv website blog blog

This repository contains our official implementation of the CVPR 2024 paper: SVGDreamer: Text-Guided SVG Generation with Diffusion Model. It can generate high-quality SVGs based on text prompts.

🆕 Update

  • [03/2024] 🔥 We have released the code for SVGDreamer.
  • [02/2024] 🎉 SVGDreamer accepted by CVPR2024. 🎉
  • [12/2023] 🔥 We have 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,

🔥 Quickstart

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
Preview:

attn-map bg init fg init bg final fg final final

Script:

python svgdreamer.py x=iconography-s1 skip_sive=False "prompt='an astronaut walking across a desert, planet mars in the background, floating beside planets, space art'" token_ind=5 result_path='./logs/astronaut_sive' seed=116740

VPSD

✍️ Iconography style

Prompt: Sydney opera house. oil painting. by Van Gogh
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 "prompt='Sydney opera house. oil painting. by Van Gogh'" result_path='./logs/SydneyOperaHouse-OilPainting' state.mprec='fp16'

✍️ Painting style

Prompt: Abstract Vincent van Gogh Oil Painting Elephant, featuring earthy tones of green and brown
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=painting "prompt='Abstract Vincent van Gogh Oil Painting Elephant, featuring earthy tones of green and brown.'" x.num_paths=256 result_path='./logs/Elephant-OilPainting'

✍️ Pixel-Art style

Prompt: Darth vader with lightsaber
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=pixelart "prompt='Darth vader with lightsaber.'" result_path='./logs/DarthVader'

✍️Low-poly style

Prompt: A picture of a bald eagle. low-ploy. polygon. minimal flat 2d vector
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=lowpoly "prompt='A picture of a bald eagle. low-ploy. polygon. minimal flat 2d vector'" neg_prompt='' result_path='./logs/BaldEagle'

✍️ Sketch style

Prompt: A free-hand drawing of A speeding Lamborghini. black and white drawing.
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=sketch "prompt='A free-hand drawing of A speeding Lamborghini. black and white drawing.'" neg_prompt='' result_path='./logs/Lamborghini'

✍️ Ink and Wash style

Prompt: Big Wild Goose Pagoda. ink style. Minimalist abstract art grayscale watercolor. empty background
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=ink "prompt='Big Wild Goose Pagoda. ink style. Minimalist abstract art grayscale watercolor. empty background'" neg_prompt='' result_path='./logs/BigWildGoosePagoda'

More Cases

See Examples.md for more cases.

🔑 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.
