A novel 3D facial animation model is proposed in this paper to generate realistic facial animation sequence. The 3D facial animation model is constructed based on morphable model and compatible with MPEG-4. Uniform mesh resampling method is put forward to align prototypic 3D faces and facial animation principle defined in MPEG-4 is adopted to drive the 3D(More)
Fatigue driving is an important reason of traffic accidents. Yawning is an evidence of driver fatigue. This paper proposes to locate and track a driver's mouth movement using a CCD camera to study on monitoring and recognizing a driver's yawning. Firstly detecting drivers' faces uses Gravity-Center template, then detecting drivers' left and right mouth(More)
Fast and accurately categorizing the millions of aerial images on Google Maps is a useful technique in pattern recognition. Existing methods cannot handle this task successfully due to two reasons: 1) the aerial images' topologies are the key feature to distinguish their categories, but they cannot be effectively encoded by a conventional visual codebook(More)
In this paper, Fisherface is extended for face recognition from one example image per person. Fisherface is one of the most successful face recognition methods. However, Fisherface requires several training images for each face, so it cannot be applied to face recognition applications where only one example image per person is available for training. To(More)
We present several improvements on the conventional morphable model. Despite having realistic results and modeling automatically in 3D face synthesis, the model construction depends on the unstable optical flow algorithm; the model is not fitting for complex illumination and the model matching procedure is time consuming. To improve the morphable model for(More)
In this paper, a novel glasses-face recognition approach eyeglasses fisherfaces, is proposed to recognize glasses-face, which treats eyeglasses as a feature of facial image, and applies fisherfaces into glasses-face images. It overcomes the choke point of removing eyeglasses which be used in previous glasses-face recognition methods. Considering the(More)
Different environment illuminations have a great impact on face detection. We present a solution based on face relighting technology. The basic idea is that there exists nine harmonic images that can be derived from a 3D model of a face, and by which we can estimate the illumination coefficient of any face sample. Using an illumination radio image, we can(More)
Nowadays, with the continual development of digital capture technologies and social media services, a vast number of media documents are captured and shared online to help attendees record their experience during events. In this paper, we present a method combining semantic inference and multimodal analysis for automatically finding media content to(More)
