    摘要： A method recognizes a face in an image. A morphable model having shape and pose parameters is fitted to a face in an image to construct a three-dimensional model of the face. Texture is extracted from the face in the image using the three-dimensional model. The shape and texture are projected into a bilinear illumination model to generate illumination bases for the face in the image. The illumination bases for the face in the image are compared to illumination bases of each of a plurality of bilinear illumination models of known faces to identify the face in the image.

    摘要： A method determines an optimal set of viewpoints to acquire a 3D shape of a face. A view-sphere is tessellated with a plurality of viewpoint cells. The face is at an approximate center of the view-sphere. Selected viewpoint cells are discarded. The remaining viewpoint cells are clustered to a predetermined number of viewpoint cells according to a silhouette difference metric. The predetermined number of viewpoint cells are searched for a set of optimal viewpoint cells to construct a 3D model of the face.

    摘要： A method reconstructs or synthesizes heads from 3D models of heads and 2D silhouettes of heads. A 3D statistical model is generated from multiple real human heads. The 3D statistical model includes a model parameter in the form of basis vectors and corresponding coefficients. Multiple 2D silhouettes of a particular head are acquired using a camera for example. The 3D statistical model is fitted to multiple 2D silhouettes to determine a particular value of the model parameter corresponding to the plurality of 2D silhouettes. Then, the 3D statistical model is rendered according to the particular value of the model parameter to reconstruct the particular head.

    摘要： A secondary battery includes an electrode assembly, which has improved safety by reducing a density of an active material centrally positioned in the electrode assembly. In the secondary battery, an electrode assembly includes a first electrode plate, a second electrode plate and a separator between the first electrode plate and the second electrode plate, the first electrode plate including a first electrode current collector and a first active material layer on the first electrode current collector, the first active material layer including a first active material, a binder and a conductive agent, and a portion of the first active material layer at a central portion of the electrode assembly including the first active material at a lower density than a density of the first active material at a portion of the first active material layer at a peripheral portion of the electrode assembly.
