Image generation from screen capture, webcam capture and/or simple brush strokes. The functions have been designed primarily for use in architecture, and for sketching in the early stages of a project. It uses Stable Diffusion and LCM-LoRA as AI backbone for the generative process. IP Adapter support is included! Initially, the Gradio code from https://github.com/flowtyone/flowty-realtime-lcm-canvas was adapted to Pyside6, and upgraded with the screen capture functionality.

Any app can be used as a design inspiration source!

Examples of screen captures that could be a great source of information for diffusion :

• Creating simple shapes in Blender
• Painting in Photoshop/Krita
• Stop a video on a specific frame
• Google Earth or Google Street View
• ...

• Install CUDA (if not done already)
• Clone the repo and install a venv.
• Install torch. Example for CUDA 11.8:

pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu118

(see https://pytorch.org/get-started/locally/)

• Install other dependencies (see requirements):
  • opencv-python
  • accelerate
  • diffusers
  • transformers
  • Pyside6. Note: It works with Pyside 6.5.2. Newer versions can cause problem with the loading of ui elements.
• Launch main.py

Screen capture a 512 x 512 window on top any app (the dimensions can be adapted depending on your GPU). By default, the capture timestep is 1 second. Then, paint with a brush or add simple shapes and see the proposed image adapting live.

CTRL + wheel to adapt cursor size. The SD model can be adapted in the lcm.py file or chosen in a drop-down menu. Voilà!

The user can choose the inference model from within the UI (beware of hard drive space!). Here are the available built-in models:
