(2023-02-15) GPEN-BFR-1024 and GPEN-BFR-2048 are now publicly available. Please download them via [ModelScope2]. (2023-02-15) We provide online demos via [ModelScope1] and [ModelScope2]. (2022-05-16) Add x1 sr model. Add --tile_size to avoid OOM. (2022-03-15) Add x4 sr model. Try --sr_scale. (2022-03-09) Add GPEN-BFR-2048 for selfies. I have to take it down due to commercial issues. Sorry about that. (2021-12-29) Add online demos Hugging Face Spaces. Many thanks to CJWBW and AK391. (2021-12-16) Release a simplified training code of GPEN. It differs from our implementation in the paper, but could achieve comparable performance. We strongly recommend to change the degradation model. (2021-12-09) Add face parsing to better paste restored faces back. (2021-12-09) GPEN can run on CPU now by simply discarding --use_cuda. (2021-12-01) GPEN can now work on a Windows machine without compiling cuda codes. Please check it out. Thanks to Animadversio. Alternatively, you can try GPEN-Windows. Many thanks to Cioscos. (2021-10-22) GPEN can now work with SR methods. A SR model trained by myself is provided. Replace it with your own model if necessary. (2021-10-11) The Colab demo for GPEN is available now google colab logo. 8.4 下载模型 Download models from Modelscope

pip install modelscope[cv] -f https://modelscope.oss-cn-beijing.aliyuncs.com/releases/repo.html Run the following codes:
import cv2 from modelscope.pipelines import pipeline from modelscope.utils.constant import Tasks from modelscope.outputs import OutputKeys
portrait_enhancement pipeline(Tasks.image_portrait_enhancement, modeldamo/cv_gpen_image-portrait-enhancement-hires) result portrait_enhancement(https://modelscope.oss-cn-beijing.aliyuncs.com/test/images/marilyn_monroe_4.jpg) cv2.imwrite(result.png, result[OutputKeys.OUTPUT_IMG]) It will automatically download the GPEN models. You can find the model in the local path ~/.cache/modelscope/hub/damo. Please note pytorch_model.pt, pytorch_model-2048.pt are respectively the 1024 and 2048 versions.
