Prompt Based Masking by clipseg

Specify advanced text based masks using boolean logic and strength modifiers. Mask syntax:

mask descriptions must be lowercase
keywords (AND, OR, NOT) must be uppercase
parentheses are supported
mask modifiers may be appended to any mask or group of masks. Example: (dog OR cat){+5} means that we’ll select any dog or cat and then expand the size of the mask area by 5 pixels. Valid mask modifiers:
- {+n} - expand mask by n pixels
- {-n} - shrink mask by n pixels
- {*n} - multiply mask strength. will expand mask to areas that weakly matched the mask description
- {/n} - divide mask strength. will reduce mask to areas that most strongly matched the mask description. probably not useful

When writing strength modifiers keep in mind that pixel values are between 0 and 1.

Click to see shell command

bash imagine "valley, fairytale treehouse village covered, , matte painting, highly detailed, dynamic lighting, cinematic, realism, realistic, photo real, sunset, detailed, high contrast, denoised, centered, michael whelan" --steps 60 --seed 1 --arg-schedule model[sd14,sd15,sd20,sd21,openjourney-v1,openjourney-v2] --arg-schedule "caption-text[sd14,sd15,sd20,sd21,openjourney-v1,openjourney-v2]"

Prompt Expansion

You can use {} to randomly pull values from lists. A list of values separated by | and enclosed in { } will be randomly drawn from in a non-repeating fashion. Values that are surrounded by _ _ will pull from a phrase list of the same name. Folders containing .txt phraselist files may be specified via --prompt_library_path. The option may be specified multiple times. Built-in categories:

3d-term, adj-architecture, adj-beauty, adj-detailed, adj-emotion, adj-general, adj-horror, animal, art-scene, art-movement,
art-site, artist, artist-botanical, artist-surreal, aspect-ratio, bird, body-of-water, body-pose, camera-brand,
camera-model, color, cosmic-galaxy, cosmic-nebula, cosmic-star, cosmic-term, desktop-background, dinosaur, eyecolor, f-stop,
fantasy-creature, fantasy-setting, fish, flower, focal-length, food, fruit, games, gen-modifier, hair, hd,
iso-stop, landscape-type, national-park, nationality, neg-weight, noun-beauty, noun-fantasy, noun-general,
noun-horror, occupation, painting-style, photo-term, pop-culture, pop-location, punk-style, quantity, rpg-item, scenario-desc,
skin-color, spaceship, style, tree-species, trippy, world-heritage-site

Examples:

imagine "a {lime|blue|silver|aqua} colored dog" -r 4 --seed 0 (note that it generates a dog of each color without repetition)

generated .jpg[].jpg[] .jpg[] .jpg[]

imagine "a {_color_} dog" -r 4 --seed 0 will generate four, different colored dogs. The colors will be pulled from an included phraselist of colors.

imagine "a {spaceship|fruit|hot air balloon}. low-poly" -r 4 --seed 0 will generate images of spaceships or fruits or a hot air balloon

Example Use Cases

>> aimg

= Generate endless 8k art
🤖🧠> imagine -w 1920 -h 1080 --upscale "{_art-scene_}. {_painting-style_} by {_artist_}" -r 1000 --steps 30 --model sd21v


= generate endless desktop backgrounds
🤖🧠> imagine --tile "{_desktop-background_}" -r 100


= convert a folder of images to pencil sketches
🤖🧠> edit other/images/*.jpg -p "make it a pencil sketch"


= upscale a folder of images
🤖🧠> upscale my-images/*.jpg


= generate kitchen remodel ideas
🤖🧠> imagine --control-image kitchen.jpg -w 1024 -h 1024 "{_interior-style_} kitchen" --control-mode depth -r 100 --init-image 0.01 --upscale --steps 35 --caption-text "{prompt}"

Additional Features

Generate images either in code or from command line.
It just works. Proper requirements are installed. Model weights are automatically downloaded. No huggingface account needed. (if you have the right hardware… and aren’t on windows)
Noisy logs are gone (which was surprisingly hard to accomplish)
WeightedPrompts let you smash together separate prompts (cat-dog)
Prompt metadata saved into image file metadata
Have AI generate captions for images aimg describe <filename-or-url>
Interactive prompt: just run aimg
finetune your own image model. kind of like dreambooth. Read instructions on "Concept Training" page

Requirements

~10 gb space for models to download
A CUDA supported graphics card with >= 11gb VRAM (and CUDA installed) or an M1 processor.
Python installed. Preferably Python 3.10. (not conda)
For macOS rust and setuptools-rust must be installed to compile the tokenizer library. They can be installed via: curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh and pip install setuptools-rust

Running in Docker

See example Dockerfile (works on machine where you can pass the gpu into the container)

docker build . -t imaginairy

= you really want to map the cache or you end up wasting a lot of time and space redownloading the model weights
docker run -it --gpus all -v $HOME/.cache/huggingface:/root/.cache/huggingface -v $HOME/.cache/torch:/root/.cache/torch -v `pwd`/outputs:/outputs imaginairy /bin/bash

feature: add progress image callback

5.0.1

fix: support larger images on M1. Fixes #8
fix: support CPU generation by disabling autocast on CPU. Fixes #81

4.0.0

feature: stable diffusion 1.5 (slightly improved image quality)
feature: dilation and erosion of masks Previously the + and - characters in a mask (example: face{+0.1}) added to the grayscale value of any masked areas. This wasn’t very useful. The new behavior is that the mask will expand or contract by the number of pixel specified. The technical terms for this are dilation and erosion. This allows much greater control over the masked area.
feature: update k-diffusion samplers. add k_dpm_adaptive and k_dpm_fast
feature: img2img/inpainting supported on all samplers
refactor: consolidates img2img/txt2img code. consolidates schedules. consolidates masking

2.1.0

improved masking accuracy from clipseg

2.0.3

fix memory leak in face enhancer
fix blurry inpainting
fix for pillow compatibility

2.0.0

🎉 fix: inpainted areas correlate with surrounding image, even at 100% generation strength. Previously if the generation strength was high enough the generated image would be uncorrelated to the rest of the surrounding image. It created terrible looking images.
🎉 feature: interactive prompt added. access by running aimg
🎉 feature: Specify advanced text based masks using boolean logic and strength modifiers. Mask descriptions must be lowercase. Keywords uppercase. Valid symbols: AND, OR, NOT, (), and mask strength modifier {+0.1} where + can be any of + - * /. Single character boolean operators also work (|, &, !)
🎉 feature: apply mask edits to original files with mask_modify_original (on by default)
feature: auto-rotate images if exif data specifies to do so
fix: mask boundaries are more accurate
fix: accept mask images in command line
fix: img2img algorithm was wrong and wouldn’t at values close to 0 or 1

1.6.2

fix: another bfloat16 fix

1.6.1

fix: make sure image tensors come to the CPU as float32 so there aren’t compatibility issues with non-bfloat16 cpus

1.6.0

fix: maybe address #13 with expected scalar type BFloat16 but found Float
- at minimum one can specify --precision full now and that will probably fix the issue
feature: tile mode can now be specified per-prompt

stem

fruit stem"
