Good evening,

First of all, I appreciate eBay publicly releasing the ModaNet dataset.

I wanted to show some examples of errors that I ran across while exploring the dataset and training clothing detectors with them. Training a mask RCNN detector with ResNet 50 backbone achieves similar results shown in Fig 4. (left) in all categories but boots and footwear (which show a significant drop in performance).

Though the polygon segmentation for some of the boxes are correct (left image below), it is sometimes the case that their corresponding bounding boxes share the same top left corner in their (though correct height and width).

Polygon Segmentation	Bounding Box

Below I am showing some errors in polygon annotations for the boots / footwear categories. In each of the following cases, the particular image_id was associated with two annotations for the boots / footwear category. Each on the two labels was did not however segment out a single shoe as can be seen below. Annotation 1/2 shows all of the polygons for a particular annotation.

Some annotations include polygons from different clothing items

Annotation 1	Annotation 2

Some annotations, though belonging to a single item, were split into different annotations

Annotation 1	Annotation 2

Below annotations contain the polygons for parts of the items.

Uh oh!
