Shape UnderstandingMotivation: Ease of 3D data acquisition (Kinect, smartphones, depth sensors, etc.) brings up a growing need for automatic algorithms that analyze the semantics and functionality of digitized shapes. Analysis algorithms, such as shape segmentation, feature detection, symmetry analysis, and surface correspondence, are employed to search, organize, synthesize, and edit 3D shapes.
Sketch-based Scene CompositionMotivation: Given the high interest to the video games and animation movies, we can safely claim that there are many people enjoying the virtual 3D world. Most of them, however, are in consumer position. By providing them an intuitive and easy-to-use 3D modelling system, we can help them be producers and reveal their creativity.
3D Scene LabelingMotivation: We want a robot to execute commands like "Fetch me the mug on the table". This requires the labeling of the raw RGB-D scene data coming from affordable scanners such as Kinect.
Facial Performance CaptureMotivation: Transfer yourself along with your mimics and movements to the other side in real-time, a different step towards holographic communication.
3D PrintingMotivation: Current 3D printer technology imposes specific constraints on digital shapes to be fabricated, e.g., size, geometry, etc. Besides, external forces such as gravity need to be simulated on the digital elastic models before printing them out to the real world. Support material optimization is also of interest.
Virtual MedicineMotivation: Exploit the dense data in medical images to the fullest and quantify medical conditions objectively in a systematic way. Give doctors a virtual practicing environment before dealing with real patients. Infer the inner body from the outer surface (X-rays, scanners), and vice versa, to decrease or eliminate unhealthy radiation. Show patient how she would look like before aesthetic surgery.
