Case Studies

USE CASE：Automatic Face Beautification.
CHALLENGE：Client hopes to further improve face beautification and Makeup synthesis technology in social products.
SOLUTION：Nexdata provides pixel-level segmentation labeling for the data provided by our customer. For the occluded objects, it is necessary to estimate most likely position for annotating and annotate the object according to the trend of contour. The gesture, body, and facial contours are strictly labeled according to shape, with smooth lines.

USE CASE：Virtual/Digital Human Modeling.
CHALLENGE：Client wants to improve the technology of virtual human modeling.
SOLUTION：The virtual human is set as an adult female. The client needs to collect facial expressions, body movements and corresponding audio data in a clean indoor environment. Nexdata completed the data collection project required by customers by using facial capture and motion capture equipment, and high-fidelity recording equipment.
