Nonrigid Structure from Motion in Trajectory Space
Existing approaches to nonrigid structure from motion assume that the instantaneous 3D shape of a deforming object is a linear combination of basis shapes, which have to be estimated anew for each video sequence. In contrast, we propose that the evolving 3D structure be described by a linear combination of basis trajectories. The principal advantage of this approach is that we do not need to es...

متن کاملMinimal structure from motion representation for image geocoding
In this extended abstract we present our early work on structure from motion data compression for image geocoding. We address the advantages of image geocoding over standard trillateration solutions and identify desired characteristics for an image geocoding system such as accuracy, speed and scalability. We hypothesize that scalability impacts both speed and accuracy and should be further rese...
متن کاملGeneric and Real-Time Structure from Motion
We introduce a generic and incremental Structure fromMotion method. By generic, we mean that the proposed method is independent of any specific camera model. During the incremental 3D reconstruction, parameters of 3D points and camera poses are refined simultaneously by a generic local bundle adjustment that minimizes an angular error between rays. This method has three main advantages: it is g...
متن کاملReconstruction of Continuous-time Chaotic Trajectory from Symbolic Sequence
z y x − − = & ay x y + = & x b z ( − + = & (1) z c) Abstract – It is shown that symbolic sequence can be used to reconstruct a trajectory of a chaotic system with high precision. Examples of construction of symbolic sequence and trajectory reconstruction are given. A method that demonstrates exponential increase in precision with the length of processing is developed. Microtriode generator is d...
