Latest Patents

One of Liu's latest patents is the "Infant 2D Pose Estimation and Posture Detection System." This innovative system employs methods for estimating an infant's pose using image analysis and artificial intelligence. A classifier is trained using a dataset that combines hybrid synthetic and real infant pose data. Multi-stage invariant representation machine learning strategies are utilized to transfer knowledge from adjacent domains of adult poses and synthetic infant images into a fine-tuned domain-adapted infant pose estimation model.

Another notable patent is the "3D Human Pose Estimation System." This system provides methods and systems for creating a dataset of human in-bed poses. It includes simultaneously gathered images of in-bed poses from various imaging modalities, such as red-green-blue (RGB) and long wavelength infrared (LWIR), depth imaging, and pressure mapping. The images are collected under specific lighting and cover conditions. This dataset can be used to train models for estimating human in-bed poses and for methods of estimating three-dimensional human poses from two-dimensional input images.
