    Two critical performance characterizations of biometric algorithms, including face recognition, are identification and verification. Identification performance of face recognition algorithms on the FERET tests has been previously reported. We report on verification performance obtained from the Sept96 FERET test. The databases used to develop and test algorithms are usually smaller than the databa... View full abstract»

    We present a face recognition method using image sequence. As input we utilize plural face images rather than a ldquosingle-shotrdquo, so that the input reflects variation of facial expression and face direction. For the identification of the face, we essentially form a subspace with the image sequence and apply the Mutual Subspace Method in which the similarity is defined by the angle between the...

    Current approaches to automated analysis have focused an a small set of prototypic expressions (e.g. joy or anger). Prototypic expressions occur infrequently in everyday life, however, and emotion expression is far more varied. To capture the full range of emotion expression, automated discrimination of fine grained changes in facial expression is needed. We developed and implemented an optical fl... View full abstract»

    This paper addresses our proposed method to automatically locate the person's face from a given image that consists of a head-and-shoulders view of the person and a complex background scene. The method involves a fast, simple and yet robust algorithm that exploits the spatial distribution characteristics of human skin color. It first uses the chrominance component of the input image to detect pixe... View full abstract»

    We propose a method to identify the human face using a 3D gray scale image which combines a 3D image with a gray scale image. The proposed method can identify facial images which face in various directions. First, 3D positions, where the eyes and the tip of the nose are located, are estimated in the acquired 3D gray scale image. Next, the calibration of facial directions and brightness is performe...

    We address the problem of robust face identification in the presence of pose, lighting, and expression variation. Previous approaches to the problem have assumed similar models of variation for each individual, estimated from pooled training data. We describe a method of updating a first order global estimate of identity by learning the class-specific correlation between the estimate and the resid... View full abstract»

    As we know, a robust approach to face and facial features detection must be able to handle the variation issues such as changes in imaging conditions, face appearances and image contents. Here we present a method which utilizes color, local symmetry and geometry information of human face based on various models. The algorithm first detects most likely face regions or ROIs (Region-Of-Interest) from... View full abstract»

    It is essential for machine lip reading to process not only static images but also moving images. This paper proposes a method, which is named Optical Snakes, for lip motion extraction from moving images using the cooperation between the active contour models called Snakes and the optical flow. The effectiveness of the method is demonstrated by the extraction of a series of lip contours from time-... View full abstract»

    The authors have proposed a physics-based facial model based on anatomical data and knowledge, which has a three dimensional structure for facial image analysis and synthesis. The skin and the skull models are constructed from 3D-CT scanned data, and the facial muscles were placed between them just like as a real human face. With regard to the skin and muscle models, spring frames are used to simu... View full abstract»

    The paper describes a real-time system which tracks the uncovered/unmarked hands of a person performing sign language. It extracts the face and hand regions using their skin colors, computes blobs and then tracks the location of each hand using a Kalman filter. The system has been tested for hand tracking using actual sign-language motion by native signers. The experimental results indicate that t... View full abstract»

    The paper describes a face recognition system that uses partial face images (for example, eye, nose, and ear images) for input data. The recognition technique is based on using radial basis function (RBF) networks. As compared with using a standard backpropagation (BP) learning algorithm, the RBF networks are far superior for the face recognition task. From the experimental results of face recogni...

    A face image can be represented by a point in a feature space such as spanned by a number of eigenfaces. In methods based on nearest neighbor classification, the representational capacity of a face database depends on how prototypical face images are chosen to account for possible image variations and also how many prototypical images or their feature points are available. We propose a novel metho... View full abstract»

    We propose a method to estimate the pose of a hand in a sequence of stereo images. This is a difficult problem since a hand is a complex object with a high number of degrees of freedom, and automatically segmenting the hand in the images is not easy. Our method is intended to solve these problems. Two video cameras feed two images to a stereo correlation algorithm, allowing the 3D reconstruction o... View full abstract»

    Speech intelligibility can be improved by adding lip image and facial image to speech signal. Thus the lip image synthesis plays an important role to realize a natural human-like face of computer agents. Moreover the synthesized lip movement images can compensate lack of auditory information for hearing impaired people. We propose a novel lip movement synthesis method based on mapping from input s...

    Facial pose and gaze point are fundamental to any visually directed human-machine interface. In this paper we propose a system capable of tracking a face and estimating the 3-D pose and the gaze point all in a real-time video stream of the head. This is done by using a 3-D model together with multiple triplet triangulation of feature positions assuming an affine projection. Using feature-based tra... View full abstract»
