چکیده

We present a methodology for articulating and posing meshes, in particular facial meshes, using sketching as input. Our method focuses on the use of two sketched curves, a reference and target curve. Our articulation system uses these curves to deform selected regions of a mesh in order to specify articulation. Likewise, our posing system uses reference and target curves to find an optimal pose in an articulation space of a mesh. This mesh can be articulated using our sketch-based approach or through alternative methods. Through our method, we seek to make articulation and posing more intuitive and simple for a novice to learn while also providing a method for more experienced users to prototype complex deformations.

3D Face Recognition Using Geodesic Facial Curves to Handle Expression, Occlusion and Pose Variations

this paper illustrates the use of radial facial curves on 3D meshes to mode facial deformation caused by expression, occlusion and variation in poses and to recognize faces despite large expression, in presence of occlusion and pose variations. Here we represent facial surface by indexed collection of radial geodesic curves on 3D face meshes emanating from nose tip to the boundary of mesh and c...

Laplacian Meshes Deformation Based on the Offset of Sketching

Surface representation and processing is one of the key topics in computer graphics and geometric modeling, since it greatly affects the range of possible applications. In this paper, we propose a new Laplacian meshes deformation based-on the offset of sketching to solve the drawback that Laplacian coordinates are not invariant under rotation. First, we correct Laplacian coordinates rotation by...

Hybridization of Facial Features and Use of Multi Modal Information for 3D Face Recognition

Despite of achieving good performance in controlled environment, the conventional 3D face recognition systems still encounter problems in handling the large variations in lighting conditions, facial expression and head pose The humans use the hybrid approach to recognize faces and therefore in this proposed method the human face recognition ability is incorporated by combining global and local ...

Current Discussions on Digital Sketching in the Early Stages of Architectural Design in Education

In the architectural design, designers are focused on the early stages of the design process or conceptual design. The ultimate goal of this stage is to find a solution for an existing problem, investigate design space, or explore an idea. This stage conventionally begins with sketches and diagrams to explore ideas and solutions; the ambiguity and vagueness of conventional freehand sketching ca...

TraceMove: A Data-assisted Interface for Sketching 2D Character Animation

In this paper we present TraceMove, a system to help novice animators create 2D, hand-drawn, character animation. The system and interface assists not only in sketching the character properly but also in animating it. A database of image frames from recorded videos of humans performing various motions, is used to provide pose silhouette suggestions as a static pose hint to the users as they dra...
