A scene containing multiple independently moving, possibly occluding, rigid objects is considered under the weak perspective camera model. We obtain a set of feature points tracked across a number of frames and address the problem of 3D motion segmentation of the objects in presence of measurement noise and outliers. We extend the robust structure from motion (SfM) method [5] to 3D motion segme...

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...

We address the problem of nonrigid Structure from Motion (SfM). Several methods have been published recently which try to solve the task of tracking, segmenting, or reconstructing nonrigid 3D objects in motion. Most of these papers focus on deformable objects. We deal with the segmentation of articulated objects, that is, nonrigid objects composed of several moving rigid objects. We consider tw...

ATLAS and CMS have each reported a modest diphoton excess consistent with the decay of a broad resonance at ∼ 750 GeV. We show how this signal can arise in a weakly coupled theory comprised solely of narrow width particles. In particular, if the decaying particle is produced offshell, then the associated diphoton resonance will have a broad, adjustable width. We present simplified models which ...

This paper describes a plan-recognition program built to explore the theory of endorsements (Cohen, 1983). The program evaluates alternative interpretations of user actions and reasons about which are the most likely explanation of the user's intentions. Uncertainty about the various alternatives was encoded in data structures called endorsements. The paper describes the workings of this progra...

Abstruct-There are a multitude of equations, methods, formulations and solutions in the literature for solving the structure from motion problem. It is shown how such methods can be mathematically related by certain changes, some of these changes preserve the essential qualities of the original system, while other changes do not. Existing methods for structure from motion are classified and ana...

Polyphenol oxidase (PPO) from tomatoes was extracted and partially purified through  (NH4)2SO4 precipitation, dialysis and ion exchange chromatography. The activity of polyphenol oxidase was investigated in solanum lycopersicum. Spectrophotometric method was used to assay the enzyme activity and the kinetic constants - maximum enzyme velocity (Vmax) and Michealis - Menten constant (Km). Of the ...
