ModaNet is a street fashion images dataset consisting of annotations related to RGB images. ModaNet provides multiple polygon annotations for each image. This dataset is described in a technical paper with the title ModaNet: A Large-Scale Street Fashion Dataset with Polygon Annotations. Each polygon is associated with a label from 13 meta fashion categories. The annotations are based on images in the PaperDoll image set, which has only a few hundred images annotated by the superpixel-based tool. The contribution of ModaNet is to provide new and extra polygon annotations for the images.

Thanks to the EvalAI team, we have ModaNet challenge leaderboard, please submit your best results there. It provides leaderboards for semantic segmentation, instance segmentation, and object detection, all in COCO-style. We also provide the per-class IOU score for semantic segmentation task in stdout File. You might need to register an account in EvalAI.

Why we made ModaNet

ModaNet is intended to serve an educational purpose by providing a benchmark annotation set for emerging computer vision research including semantic segmentation, object detection, instance segmentation, polygon detection, and etc.

Access to the annotations git repo

Please first install Git Large File Storage by following the below instructions. You might need to apply this step before you download the sql file from paperdoll repo.

https://help.github.com/articles/installing-git-large-file-storage/

Then you should git clone the repo along with the annotation files, otherwise the annotation files would not be downloaded directly using git clone.

git clone git@github.com:eBay/modanet.git 

Before you start working on the dataset, please verify the annotation files by using md5sum. In Mac, this requires you to run the following command:

md5 modanet2018_instances_train.json

you should expect to see the following md5 value:

MD5 (modanet2018_instances_train.json) = 96478657d20e322e9d3282c6d73c0c4c

If you apply the same command to check the val annotation, you should expect to see:

MD5 (modanet2018_instances_val.json) = 900b24b7d6c0c48203e6244f45d65499

Notice the file size:

modanet2018_instances_train.json (101MB)
modanet2018_instances_val.json (210KB)

Labels

Each polygon (bounding box, segmentation mask) annotation is assigned to one of the following labels:

The annotation data format of ModaNet follows the same style as COCO-dataset.
