Open yinguobing opened 4 years ago

yinguobing commented 4 years ago

How can I use the LFPW facial landmark dataset? Dataset: https://ibug.doc.ic.ac.uk/resources/facial-point-annotations/

yinguobing commented 4 years ago

The raw data you downloaded from the official website should be a single zip file named lfpw.zip of size 359.6MB.

Unzip it, You will get a directory named lfpw.

unzip lfpw.zip

There are two directories in it:

testset  trainset

The trainset contains 811 png files and 811 pts files, while testset contains 224 png files and 224 pts files.

To take a peek of all the files:

python3 image_utility/count_files.py /home/robin/data/facial-marks/lfpw/
Total files: 2070
{'png': 1035, 'pts': 1035}
Done!
