    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...

    The authors propose a framework for fast view alignment using adaptive affine tracking. They address the issue of modelling both shape and texture information in eigenspace for view alignment. They present an effective bootstrapping process based on colour segmentation and selective attention. They recover affine parameters with dynamic updates to the eigenspace using most recent history and perfo... View full abstract»

    This paper describes experiments in human motion understanding, defined here as estimation of the physical state of the body (the Plant) combined with interpretation of that part of the motion that cannot be predicted by the plant alone (the Behavior). The described behavior system operates in conjunction with a real-time, fully-dynamic, 3-D person tracking system that provides a mathematically co... View full abstract»

    The author describes a prototype system for directing a computer generated scene for film planning. The system is based upon the concepts of the intuitive interface, an environment in which the user interacts in front of a projection screen, and where interaction in physical space and pointing gestures are used to direct the scene. The environment demands certain requirements of the interaction pa... View full abstract»

    An algorithm is proposed for facial feature detection from a facial image. The algorithm consists of the bottom-up and the top-down interpretation processes, which work with the feature matching module and the structure matching module. Experimental results show that the proposed algorithm can detect no less than five features in 99.3% of the frontal views and can work even if the face orientation... View full abstract»

    The recognition of human gestures in image sequences is an important and challenging problem that enables a host of human-computer interaction applications. This paper describes an incremental recognition strategy that is an extension of the “Condensation” algorithm proposed by Isard and Blake (1996). Gestures are modeled as temporal trajectories of some estimated parameter over time (... View full abstract»

    We propose a human motion detection method using multiple-viewpoint images. In vision-based human tracking, self-occlusions and human-human occlusions are a part of the more significant problems. Employing multiple viewpoints and a viewpoint selection mechanism, however, can reduce these problems. The vision system in this case should select the best viewpoints for extracting human motion informat... View full abstract»

  • Finding pose of hand in video images: a stereo-based approach

    Publication Year: 1998, Page(s):585 - 590
    Cited by:  Papers (19)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (252 KB)

    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»

    The paper presents preliminary work on a novel technique for gaze estimation from a single image. The goal is to provide rough estimates of where a person is looking at a monitor. Many applications for human-computer interaction are possible for such a technique. The approach uses the morphable model framework of Jones and Poggio (1998) to model a region around the eyes of a person. After matching... View full abstract»

    We present a robust approach to estimate the 3D pose of human heads in a single image. In contrast with other research, this method only makes use of the information about the skin region and the hair region of heads. At first, we use an efficient algorithm based on a perceptually uniform color system and fuzzy theory to extract the skin region and hair region, which are then used to detect faces ...

    The capability of recognition is critical in learning but variation of sensory input makes recognition a very challenging task. The current technology in computer vision and pattern recognition requires humans to collect images, store images, segment images for computers and train computer recognition systems using these images. It is unlikely that such a manual labor process can meet the demands ... 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 new method for extracting human silhouettes from color images in real-time regardless of changes in lighting conditions and backgrounds is proposed. In the method, RGB values of each pixel in color images acquired by a CCD camera are converted to YIQ values. Before extracting human silhouettes, the mean YIQ values of each pixel and the threshold values for the Y, I, Q components are obtained in ... View full abstract»

    A new technique for description and recognition of human gestures is presented. First, a method is proposed to represent gestures as an ordered sequence of simple basic motions. It is based on the rate of change of gesture motion direction (referred to as “curvature”) that is estimated using optical flow from monocular motion images. Then, proceeding from the method, a real-time gestur... View full abstract»

    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»

    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»

    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.

    The importance of gesture protocols has caught little attention in the field of gesture-related computer vision research. The gesture protocols are the consensus on gestures, which are formed through face-to-face communication in our daily lives. Traditional gesture recognition algorithms unilaterally presupposed the gesture protocol without the consensus from users. As a consequence, users were d... View full abstract»

    The paper presents a real time gesture recognition method for interactive systems which can perform an interaction like human communication. This method recognizes a user's gesture using the eigenspace constructed from multi-input image sequences. Since this eigenspace represents the approximate 3D information of gesture, complicated gestures which may have self-occlusion and confusion in a single... View full abstract»
