It has the following properties: +1. It contains 44,096 high-resolution human images, including 12,701 full body human images. +2. For each full body images, we **manually annotate** the human parsing labels of 24 classes. +3. For each full body images, we **manually annotate** the keypoints. +4. We extract DensePose for each human image. +5. Each image is **manually annotated** with attributes for both clothes shapes and textures. +6. We provide a textual description for each image. + + + +Please refer to [this repo](https://github.com/yumingj/DeepFashion-MultiModal) for more details about our proposed dataset. + +## TODO List + +-
