ARCosmetics: a real-time augmented reality cosmetics try-on system

A virtual cosmetics try-on system provides a realistic try-on experience for consumers and helps them efficiently choose suitable cosmetics. In this article, we propose a real-time augmented reality virtual cosmetics try-on system for smartphones (ARCosmetics), taking speed, accuracy, and stability into consideration at each step to ensure a better user experience. A novel and very fast face tracking method utilizes the face detection box and the average position of facial landmarks to estimate the faces in continuous frames. A dynamic weight Wing loss is introduced to assign a dynamic weight to every landmark by the estimated error during training. It balances the attention between small, medium, and large range error and thus increases the accuracy and robustness. We also designed a weighted average method to utilize the information of the adjacent frame for landmark refinement, guaranteeing the stability of the generated landmarks. Extensive experiments conducted on a large 106-point facial landmark dataset and the 300-VW dataset demonstrate the superior performance of the proposed method compared to other state-of-the-art methods. We also conducted user satisfaction studies further to verify the efficiency and effectiveness of our ARCosmetics system.
