Image Transmission Based on Spiking Dynamics of Electrically Controlled VCSEL-SA Neuron
Photonics, 2021 Based on the spiking dynamics of the electrically controlled vertical-cavity surface-emitting laser with an embedded saturable absorber (VCSEL-SA), we propose an image transmission system using two unidirectionally coupled VCSEL-SAs and numerically ...

Adaptive Rate Polar Code for DCT-Based Digital Image Transmission
IEEE Access, 2023 Polar code is a recent forward error correction technique that is characterized by its low encoding/decoding complexity and good error performance. In this paper, a complete image transmission system (transmitter and receiver) is proposed to improve the ...

Direct transmission of pictorial information in multimode optical fibers [PDF]
, 1976 The problem of coherent image transmission through a single multimode optical fiber is discussed. A scheme is presented for recovering the transmitted image after distortions brought about by the fiber modes dispersion.

Three-dimensional pictorial transmission in optical fibers [PDF]
, 1976 Modal phase dispersion limits image transmission in optical fibers to distances too short to be of general interest. A technique based on nonlinear optical mixing is described for modal phase equalization and recovery of a transmitted ...

A reduced-reference perceptual image and video quality metric based on edge preservation [PDF]
, 2012 In image and video compression and transmission, it is important to rely on an objective image/video quality metric which accurately represents the subjective quality of processed images and video sequences.

Epipolar Consistency in Transmission Imaging [PDF]
IEEE Transactions on Medical Imaging, 2015 This paper presents the derivation of the Epipolar Consistency Conditions (ECC) between two X-ray images from the Beer-Lambert law of X-ray attenuation and the Epipolar Geometry of two pinhole cameras, using Grangeat's theorem. We motivate the use of Oriented Projective Geometry to express redundant line integrals in projection images and define a ...

The optical microscopy with virtual image breaks a record: 50-nm resolution imaging is demonstrated [PDF]
, 2010 We demonstrate a new 'microsphere nanoscope' that uses ordinary SiO2 microspheres as superlenses to create a virtual image of the object in near field. The magnified virtual image greatly overcomes the diffraction limit. We are able to resolve clearly 50-

Differential Binary Encoding Method for Calibrating Image Sensors Based on IOFBs
Sensors, 2012 Image transmission using incoherent optical fiber bundles (IOFBs) requires prior calibration to obtain the spatial in-out fiber correspondence necessary to reconstruct the image captured by the pseudo-sensor.
