A simple face aligment method, based on pytorch
The train project has been integrated to mmpose/skps. And the codes will be reconstructed soon.
The keypoint model encodes and decodes the x and y coordinates using heatmap and offset of x and y, achieving SOTA on WFLW dataset. Like object detection, heatmap predicts which point is a positive sample on the featuremap, represented as a highlighted area, while x and y offsets are responsible for predicting the specific coordinates of these positive samples. And it achieves ** NME 3.95 on WFLW ** with no extern data. Contact me if u have problem about it. 2120140200@mail.nankai.edu.cn :)

Download WFLW data. Set them in train_config.py.

then
run.sh -
by default it is trained with mobilenetv3-large as student, efficientnetb5 as teacher.
