Automatic facial expression recognition (FER) plays an important role in many fields. However, most existing FER techniques are devoted to the tasks in the constrained conditions, which are different from actual emotions. To simulate the spontaneous expression, the number of samples in acted databases is usually small, which limits the ability of facial(More)
Since the introduction of isogeometric analysis (IGA) by Hughes et al. in 2005 [1], one of the most promising directions of research in computational mechanics during the recent years has been towards the synthesis of the CAD geometry and methods of stress analysis (see [2] for a review of work in this area). IGA utilizes the same functions for representing(More)
