Abstract EN
Generating extreme appearances such as scared awaiting sweating while happy fit for tears (cry) and blushing (anger and happiness) is the key issue in achieving the high quality facial animation.
The effects of sweat, tears, and colors are integrated into a single animation model to create realistic facial expressions of 3D avatar.
The physical properties of muscles, emotions, or the fluid properties with sweating and tears initiators are incorporated.
The action units (AUs) of facial action coding system are merged with autonomous AUs to create expressions including sadness, anger with blushing, happiness with blushing, and fear.
Fluid effects such as sweat and tears are simulated using the particle system and smoothed-particle hydrodynamics (SPH) methods which are combined with facial animation technique to produce complex facial expressions.
The effects of oxygenation of the facial skin color appearance are measured using the pulse oximeter system and the 3D skin analyzer.
The result shows that virtual human facial expression is enhanced by mimicking actual sweating and tears simulations for all extreme expressions.
The proposed method has contribution towards the development of facial animation industry and game as well as computer graphics.
