Fourier-invariant autofocused Laguerre-Gaussian beams
Компьютерная оптикаWe study a new Laguerre - Gaussian (LG) beam, which differs from conventional LG mode beams that preserve the structure of the intensity distribution up to scale.

Unsupervised Saliency Model with Color Markov Chain for Oil Tank Detection
Remote Sensing, 2019 Traditional oil tank detection methods often use geometric shape information. However, it is difficult to guarantee accurate detection under a variety of disturbance factors, especially various colors, scale differences, and the shadows caused by view ...

Snapshot multispectral imaging using a filter array [PDF]
International Workshop on Image Sensors and Imaging Systems
(IWISS2018), 2018 A multispectral filter array (MSFA) is one solution for capturing a multispectral image (MSI) in a single shot at low cost. We introduce our optimization method of the spectral sensitivity of the MSFAs and demosaicking, and show a new prototype filter array for snapshot imaging based on a photonic crystal.

Methods for Earth-Observing Satellite Surface Reflectance Validation
Remote Sensing, 2019 In this study an initial validation of the Landsat 8 (L8) Operational Land Imager (OLI) Surface Reflectance (SR) product was performed. The OLI SR product is derived from the L8 Top-of-Atmosphere product via the Landsat Surface Reflectance Code (LaSRC ...

A Comprehensive Review of Image Enhancement Techniques [PDF]
Journal of Computing, Volume 2, Issue 3, March 2010,
https://sites.google.com/site/journalofcomputing/, 2010 Principle objective of Image enhancement is to process an image so that result is more suitable than original image for specific application. Digital image enhancement techniques provide a multitude of choices for improving the visual quality of images.

Convolutional neural networks model improvements using demographics and image processing filters on chest x-rays [PDF]
arXiv, 2019 Purpose: The purpose of this study was to observe change in accuracies of convolutional neural networks (CNN) models (ratio of correct classifications to total predictions) on thoracic radiological images by creating different binary classification models based on age, gender, and image pre-processing filters on 14 pathologies. Methodology: This is a

Deep Camera: A Fully Convolutional Neural Network for Image Signal Processing [PDF]
arXiv, 2019 A conventional camera performs various signal processing steps sequentially to reconstruct an image from a raw Bayer image. When performing these processing in multiple stages the residual error from each stage accumulates in the image and degrades the quality of the final reconstructed image.
