Determining the Singularities for the Observation of Three Image Lines [PDF]
IEEE Robotics and Automation Letters, 2017 The determination of the singularity cases in the observation of image features is a complicated problem which is still open, apart from image points. For the first time, we provide the singularity cases in the observation of three image lines. We show that a concept named the "hidden robot", which was formerly used for understanding the singularities ...

Polarized image of equatorial emission in horizonless spacetimes: Naked singularities [PDF]
Physical Review D, 2023 We study the linear polarization from the accretion disk around weakly and strongly naked Janis-Newman-Winicour singularities. We consider an analytical toy model of thin magnetized fluid ring orbiting in the equatorial plane and emitting synchrotron ...

Improving the Manipulability of a Redundant Arm Using Decoupled Hybrid Visual Servoing
Applied Sciences, 2021 This study proposes a hybrid visual servoing technique that is optimised to tackle the shortcomings of classical 2D, 3D and hybrid visual servoing approaches.

Shadows of spherically symmetric black holes and naked singularities [PDF]
Monthly notices of the Royal Astronomical Society, 2018 We compare shadows cast by Schwarzschild black holes with those produced by two classes of naked singularities that result from gravitational collapse of spherically symmetric matter.

Deformations of symplectic singularities and orbit method for semisimple Lie algebras [PDF]
Selecta Mathematica, 2016 We classify filtered quantizations of conical symplectic singularities and use this to show that all filtered quantizations of symplectic quotient singularities are spherical symplectic reflection algebras of Etingof and Ginzburg.

Fast and simple super-resolution with single images
Scientific Reports, 2022 We present a fast and simple algorithm for super-resolution with single images. It is based on penalized least squares regression and exploits the tensor structure of two-dimensional convolution. A ridge penalty and a difference penalty are combined; the

An Edge Driven Wavelet Frame Model for Image Restoration [PDF]
Applied and Computational Harmonic Analysis, 2017 Wavelet frame systems are known to be effective in capturing singularities from noisy and degraded images. In this paper, we introduce a new edge driven wavelet frame model for image restoration by approximating images as piecewise smooth functions. With
