+
+<!-- Provide a quick summary of what the model is/does. -->
+
+Hello, I am very happy to announce the controlnet-canny-sdxl-1.0 model, **a very powerful controlnet that can generate high resolution images visually comparable with midjourney**. 
+The model was trained with large amount of high quality data(over 10000000 images), with carefully filtered and captioned(powerful vllm model). Besides, useful tricks are applied 
+during the training, including date augmentation, mutiple loss and multi resolution. With only 1 stage training, the performance outperforms the other opensource canny models
+([diffusers/controlnet-canny-sdxl-1.0], [TheMistoAI/MistoLine]). I release it and hope to advance the application of stable diffusion models. Canny is one of the most important 
+ControlNet series models and can be applied to many jobs associated with drawing and designing.

+
+## Evaluation Metric
+1 Laion Aesthetic Score [https://laion.ai/blog/laion-aesthetics/]  
+2 PerceptualSimilarity [https://github.com/richzhang/PerceptualSimilarity]
+
+
+## Evaluation Data
+The test data is randomly sample from midjourney upscale images with prompts, as the purpose of the project is to letting people draw images like midjourney. midjourney’s users include a large number of professional designers,
+and the upscale image tend to have more beauty score and prompt consistency, it is suitable to use it as the test set to judge the ability of controlnet. We select 300 prompt-image pairs randomly and generate 4 images per prompt,
+totally 1200 images generated. We caculate the Laion Aesthetic Score to measure the beauty and the PerceptualSimilarity to measure the control ability, we find the quality of images have a good consistency with the meric values.
+We compare our methods with other SOTA huggingface models and list the result below. We are the models that have highest aesthectic score, and can generate visually appealing images if you prompt it properly.
+
+## Quantitative Result
+| metric | xinsir/controlnet-canny-sdxl-1.0 | diffusers/controlnet-canny-sdxl-1.0 | TheMistoAI/MistoLine |
+|-------|-------|-------|-------|
+| laion_aesthetic | **6.03** | 5.93 | 5.82 |
+| perceptual similarity | **0.4200** | 0.5053 | 0.5387 |
+
+laion_aesthetic(the higher the better)  
+perceptual similarity(the lower the better)
+Note: The values are calculate when saved in webp format, if you save in png format the aesthetic values will increase 0.1-0.3 but the relative relation remains unchanged.
+
+
+## Training Details
+
+The model is trained using high quality data, only 1 stage training, the resolution setting is the same with sdxl-base, 1024*1024. We use random threshold to generate canny images like lvming zhang, It is essential to find proper hyerparameters 
+to realize data augmentation, too easy or too hard will hurt the model performance. Besides, we use random mask to random mask out a random percentage of canny images to force the model to learn more semantic meaning between the prompt and the line.
+We use over 10000000 images, which are annotated carefully, cogvlm is proved to be a powerful image caption model[https://github.com/THUDM/CogVLM?tab=readme-ov-file]. For comic images, it is recommened to use waifu tagger to generate special tags
+[https://huggingface.co/spaces/SmilingWolf/wd-tagger]. More than 64 A100s are used to train the model and the real batch size is 2560 when used accumulate_grad_batches.
+
+
+### Training Data
+
+<!-- This should link to a Dataset Card, perhaps with a short stub of information on what the training data is all about as well as documentation related to data pre-processing or additional filtering. -->
+
+The data consists of many sources, including midjourney, laion 5B, danbooru, and so on. The data is carefully filtered and annotated. 
+
+
+### Conclusion
+
+<!-- This relates heavily to the Technical Specifications. Content here should link to that section when it is relevant to the training procedure. -->
+
+In our evaluation, the model got better aesthetic score in real images compared with stabilityai/stable-diffusion-xl-base-1.0,  and comparable performance in cartoon sytle images.
+The model is better in control ability when test with perception similarity due to more strong data augmentation and more training steps. 
+Besides, the model has lower rate to generate abnormal images which tend to include some abnormal human structure.
