# Diffusers ControlNet Impl. & Reference Impl. generated image comparison

## Implementation Source Code & versions
- Diffusers (in development version): https://github.com/takuma104/diffusers/tree/e758682c00a7d23e271fd8c9fb7a48912838045c
- Reference Impl.: https://github.com/lllyasviel/ControlNet/tree/2f77609bf6a8a2243d9faa198365fc6222c5435f

## Environment
- OS: Ubuntu 22.04
- GPU: Nvidia RTX3060 (12GB)

## Scripts to generate plots:
- Create control image: [create_control_images.py](create_control_images.py)
- Diffusers generated image: [gen_diffusers_image.py](gen_diffusers_image.py)
- Reference generated image: [gen_reference_image.py](gen_reference_image.py)
- Create Plots: [create_plots.py](create_plots.py)

## Original image for control image:
- All images from [test_imgs](https://github.com/lllyasviel/ControlNet/test_imgs) excepts vermeer image. Croped and resized to 512x512px.

## Generate Settings:
#### Control Images:
Converted above original images by [controlnet_hinter](https://github.com/takuma104/controlnet_hinter).

#### Prompts:
All images were generated with the same prompt.

- Prompt: `best quality, extremely detailed, illustration, looking at viewer`
- Negative Prompt: `monochrome, lowres, bad anatomy, worst quality, low quality`

#### Ohter setting (both common):
- sampler: DDIM
- guidance_scale: 9.0
- num_inference_steps: 20
- initial random latents: created on CPU using seed
