An automatic three-dimensional (3D) model reconstruction technique is presented to acquire complete and closed 3D models of real objects. The technique is based on novel approaches to pose estimation and integration. Two different poses of an object are used because a single pose often hides some surfaces from a range sensor. A second pose is used to expose such surfaces to the sensor. Two part...

In this paper, we present a method to generate novel realistic 3D face model using a model trained from real 3D face data. 3D face samples are an important data platform for model training, algorithm design. Subject to the constraint of acquisition technology, sizes of current 3D face databases are relatively small and insufficient. The presented method is used to solve this problem. First real...

We introduce a 3D model-based approach for automatic segmentation of 3D fluorescent heterochromatin foci from 3D microscopy images. The approach employs a new 3D parametric intensity model based on a spherical harmonics (SH) expansion and can represent foci of regular and highly irregular shapes. By solving a least-squares optimization problem, the model is directly fitted to the 3D image data,...

Hand tracking has great potential as a tool for better human-computer interaction. Areas of application include navigation in virtual environments, gesture recognition and motion capture for film animation. This report presents a new method for 3D hand tracking. It uses a 3D model built from truncated quadrics which approximates the anatomy of a real human hand. This approach allows for the use...

Estimating the structure of the human face is a long studied and difficult task. In this paper we present a new method for estimating facial structure from only a minimal number of salient feature points across a video sequence. The presented method uses both an Extended Kalman Filter (EKF) and a Kalman Filter (KF) to regress 3D Morphable Model (3DMM) shape parameters and solve 3D pose using a ...

A personal identiication system based on the analysis of frontal or proole images of the face has applications in human-computer interfaces, access control , surveillance etc. Among many practical face recognition schemes, image based approaches are possibly the most promising ones. However, the 2D im-ages/patterns of 3D face objects can change dramatically due to lighting and viewing variation...

While an exact definition of texture is somewhat elusive, texture can be qualitatively described as a distribution of color, albedo or local normal on a surface. In the literature, the word texture is often used to describe a color or albedo variation on a smooth surface. We refer to such texture as 2D texture. In real world scenes, texture is often due to surface height variations and can be t...
