This article describes a pipeline that receives as input a sequence of images acquired by a calibrated stereo rig and outputs the camera motion and a Piecewise-Planar Reconstruction (PPR) of the scene. It firstly detects the 3D planes viewed by each stereo pair from semi-dense depth estimation. This is followed by estimating the pose between consecutive views using a new closed-form minimal alg...

The Half-Plane Half-Comb walk is a random on the plane, when we have square lattice upper half-plane and comb structure lower half-plane, i.e., horizontal lines below x-axis are removed. We prove that probability this returns to origin in 2N steps asymptotically equal $$2/(\pi N).$$ 2 / ( ? N ) . As consequence, strong laws limit distribution for local time.

Topological information are the most important kind of qualitative spatial information. Current formalisms for the topological aspect of space focus on relations between regions or properties of regions. This work provides a qualitative model for representing the topological internal structure of complex regions, which could be of multiple pieces and/or have holes and islands to any finite leve...

We study the vacuum, plane-wave Bianchi V IIh spacetimes described by the Lukash metric. By combining covariant with orthonormal frame techniques, we describe these models in terms of their irreducible kinematical and geometrical quantities. This covariant description is used to study analytically the response of the Lukash spacetime to linear perturbations. We find that the stability of the va...

An electrically thin chiral metamaterial structure composed of four U-shaped split ring resonator pairs is utilized in order to realize polarization rotation that is dependent on the polarization of the incident wave at 6.2 GHz. The structure is optimized such that a plane wave that is linearly polarized at an arbitrary angle is an eigenwave of the system at this frequency. The analytical relat...

Recently there has been much interest in 3D reconstruction from uncalibrated views. Relative AAne Structure has been proposed 1] as an alternative framework to projective reconstruction. Proposed algorithms in 1, 2] were based on an oo-line feature corresponding process. This paper extends the relative aane structure from motion to a `correspondenceless' 1 framework. A `projected planar patch o...

The fabrication of a muffin-tin planar accelerator structure for operation in the 90 GHz range is discussed in Reference. [1]. Fabrication problems subsequently encountered led us to consider an alternative structure, a structure which can be thought of as a muffin-tin with the sides removed and replaced by a pair of side chambers which act as side terminations (Fig. 1). With the side chambers ...

In the crystal structure of the title compound, C22H13Br2N3, the two bromo-phenyl rings are rotated out of the plane of the central benzyl-idene ring by 68.7 (1) and 69.3 (1)°. Both cyano substituents are located nearly in the plane of the benzylidene ring, with the mean plane of the methylmalononitrile group being inclined to this ring by 5.8 (1)°. In the crystal, the mol-ecules are linked by ...

Background in music performance research For the past few decades there has been considerable scientific interest in expression in music performance (Gabrielsson, 2003). A particularly relevant aspect of music performance is expressive timing, that is, the fluctuations of tempo during a performance. Accordingly, expressive timing has been one of the major topics in music performance research. A...

Training the classifier requires ground truth data. We have investigated the use of advanced rendering techniques for generation of ground truth motion fields from synthetic images [3]. The DIPLECS project The DIPLECS project entails the design of a cognitive system capable of learning and adapting to everyday situations, with particular application to driving scenarios. One of the goals of the...
