Single Image Generation

By using the following command, you can quickly generate an image with MIGC.

CUDA_VISIBLE_DEVICES=0 python inference_single_image.py

The following is an example of the generated image based on stable diffusion v1.4.

? Enhanced Attribute Control: For those seeking finer control over attribute management, consider exploring the python inferencev2_single_image.py script. This advanced version, InferenceV2, offers a significant improvement in mitigating attribute leakage issues. By accepting a slight increase in inference time, it enhances the Instance Success Ratio from 66% to an impressive 68% on COCO-MIG Benchmark. It is worth mentioning that increasing the NaiveFuserSteps in inferencev2_single_image.py can also gain stronger attribute control.

? Versatile Image Generation: MIGC stands out as a plug-and-play controller, enabling the creation of images with unparalleled variety and quality. By simply swapping out different base generator weights, you can achieve results akin to those showcased in our Gallery. For instance:

• ? RV60B1: Ideal for those seeking lifelike detail, RV60B1 specializes in generating images with stunning realism.
• ? Cetus-Mix and Ghost: These robust base models excel in crafting animated content.

COCO-MIG Bench

To validate the model's performance in position and attribute control, we designed the COCO-MIG benchmark for evaluation and validation.

By using the following command, you can quickly run inference on our method on the COCO-MIG bench:

CUDA_VISIBLE_DEVICES=0 python inference_mig_benchmark.py

We sampled 800 images and compared MIGC with InstanceDiffusion, GLIGEN, etc. On COCO-MIG Benchmark, the results are shown below.

MIGC-GUI

We have combined MIGC and GLIGEN-GUI to make art creation more convenient for users. ?This GUI is still being optimized. If you have any questions or suggestions, please contact me at zdw1999@zju.edu.cn.

Stat with MIGC-GUI

Step 1: Download the MIGC_SD14.ckpt and place it in pretrained_weights/MIGC_SD14.ckpt. ?If you have already completed this step during the Installation phase, feel free to skip it.

Step 2: Download the CLIPTextModel and place it in migc_gui_weights/clip/text_encoder/pytorch_model.bin.

Step 3: Download the CetusMix model and place it in migc_gui_weights/sd/cetusMix_Whalefall2.safetensors. Alternatively, you can visit civitai to download other models of your preference and place them in migc_gui_weights/sd/.

├── migc_gui
│   ├── app.py

Step 4: cd migc_gui

Step 5: Launch the application by running python app.py --port=3344. You can now access the MIGC GUI through http://localhost:3344/. Feel free to switch the port as per your convenience.

MIGC + LoRA

MIGC can achieve powerful attribute-and-position control capabilities while combining with LoRA. ? We will integrate this function into MIGC-GUI in the future, so stay tuned! ??

Ethical Considerations

The broad spectrum of image creation possibilities offered by MIGC might present comparable ethical dilemmas to those encountered with numerous other methods of generating images from text.
