This task aims to predict the segmentation map of an image containing dark complexion portrait.

Data Description

To stimulate the dark complexion portrait segmentation research, we collect the images with dark complexion portrait to establish the benchmark for dark complexion portrait segmentation. Our Dark Complexion Portrait Segmentation Dataset (DCPS) contains 12165 training and 2570 test images, in which there are 14735 dark complexion portrait images in total.

You can download the dataset at DCPS(Google Drive) or DCPS(Baidu Drive). The Baidu Drive extract password is fh52.

Dataset Examples

Evaluation Metric

For this task, we use Mean IoU(%) for dark complexion portrait segmentation evaluation.

  • Mean IoU(%) for semantic part segmentation, reported by the FCN paper.

Submission Format

The results should be pack into a single zip file. Example zip file is available in

Specifically, the zip file contains one sub-folder in it:

A folder of png images, named as "segmentation". The content of id.png is the segmentation results for the image with exactly the same size.

After uploading you results, please wait for 10 to 20 minutes and refrash your page to see the scores.
