300W Dataset is a database consisting of AFLW, AFW, Helen, IBUG, LFPW, LFW and other datasets, released by the iBUG team in 2016.

The related challenge for this dataset is the Automatic Facial Landmark Detection in the Wild Challenge. The first challenge was held in conjunction with the 2013 Sydney Computer Vision Conference. Automatic facial landmark detection is a major challenge in the field of computer vision, and the 300-W Challenge is a benchmark specifically for work in this field, especially facial images captured in the wild.
