Any human face can be considered to be a combination of these standard faces. For example, one's face might be composed of the average face plus 10% from eigenface 1, 55% from eigenface 2, and even −3% from eigenface 3. Remarkably, it does not take many eigenfaces combined together to achieve a fair approximation of most faces.
Their work is the first to introduce a statistical model for faces that enabled 3D reconstruction from 2D images and a parametric face space for controlled manipulation. [ 2 ] In the original definition of Blanz and Vetter, [ 1 ] the shape of a face is represented as the vector S = ( X 1 , Y 1 , Z 1 , . . .
A face is a bounded portion of a surface; an edge is a bounded piece of a curve and a vertex lies at a point. Other elements are the shell (a set of connected faces), the loop (a circuit of edges bounding a face) and loop-edge links (also known as winged edge links or half-edges) which are used to create the edge circuits. [2]
A position (usually in 3D space) along with other information such as color, normal vector and texture coordinates. edge A connection between two vertices. face A closed set of edges, in which a triangle face has three edges, and a quad face has four edges. A polygon is a coplanar set of faces. In systems that support multi-sided faces ...
In the norm-based model, the encoding of faces is relative to a central face at the origin: a ‘norm face’. [1] Faces are arranged using vectors from this norm, with the vector’s parameters of length and direction determined by the distinctiveness and features of the face respectively. [3] In the exemplar-based model, faces are encoded as ...
Computer facial animation is primarily an area of computer graphics that encapsulates methods and techniques for generating and animating images or models of a character face. The character can be a human , a humanoid, an animal , a legendary creature or character, etc. Due to its subject and output type, it is also related to many other ...
In elementary geometry, a face is a polygon [note 1] on the boundary of a polyhedron. [3] [4] Other names for a polygonal face include polyhedron side and Euclidean plane tile. For example, any of the six squares that bound a cube is a face of the cube. Sometimes "face" is also used to refer to the 2-dimensional features of a 4-polytope.
The input is an RGB image of the face, scaled to resolution , and the output is a real vector of dimension 4096, being the feature vector of the face image. In the 2014 paper, [ 13 ] an additional fully connected layer is added at the end to classify the face image into one of 4030 possible persons that the network had seen during training time.
