tl;dr: A large scale (15k training images) dataset for crowded/dense human detection.

Overall impression

Very solid technical report from megvii (face++). Related datasets: WiderPerson.

Previous datasets are more likely to annotate crowd human as a whole ignored region, which cannot be counted as valid samples in training and evaluation.
