An Image Forensic Technique Based on JPEG Ghosts [PDF]
arXiv, 2021 The unprecedented growth in the easy availability of photo-editing tools has endangered the power of digital images.An image was supposed to be worth more than a thousand words,but now this can be said only if it can be authenticated orthe integrity of the image can be proved to be intact. In thispaper, we propose a digital image forensic technique for

Three-dimensional images of choanoflagellate loricae [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2008 Choanoflagellates are unicellular filter-feeding protozoa distributed universally in aquatic habitats. Cells are ovoid in shape with a single anterior flagellum encircled by a funnel-shaped collar of microvilli. Movement of the flagellum creates water currents from which food particles are entrapped on the outer surface of the collar and ingested by ...

Underwater Image Enhancement Using Convolutional Neural Network [PDF]
arXiv, 2021 This work proposes a method for underwater image enhancement using the principle of histogram equalization. Since underwater images have a global strong dominant colour, their colourfulness and contrast are often degraded. Before applying the histogram equalisation technique on the image, the image is converted from coloured image to a gray scale image

A Review of Image Mosaicing Techniques [PDF]
arXiv, 2014 Image Mosaicing is a method of constructing multiple images of the same scene into a larger image. The output of the image mosaic will be the union of two input images. Image-mosaicing algorithms are used to get mosaiced image. Image Mosaicing processed is basically divided in to 5 phases.

A Privacy-Preserving Image Retrieval Scheme with a Mixture of Plain and EtC Images [PDF]
arXiv, 2022 In this paper, we propose a novel content-based image-retrieval scheme that allows us to use a mixture of plain images and compressible encrypted ones called "encryption-then-compression (EtC) images." In the proposed scheme, extended SIMPLE descriptors are extracted from EtC images as well as from plain ones, so the mixed use of plain and encrypted ...

Retrieval Guided Unsupervised Multi-domain Image-to-Image Translation [PDF]
arXiv, 2020 Image to image translation aims to learn a mapping that transforms an image from one visual domain to another. Recent works assume that images descriptors can be disentangled into a domain-invariant content representation and a domain-specific style representation.

Demonstration of literal three-dimensional imaging
Applied Optics, 1999 In a recent paper a new technique was proposed for remote ranging and topographical mapping by using a system with a single-photon-counting detector and a low-power pulsed laser [Appl. Opt. 35, 441 (1996)]. We report on the results from the laboratory and the field demonstration of this literal three-dimensional imaging technique.

Machine learning on images using a string-distance [PDF]
arXiv, 2013 We present a new method for image feature-extraction which is based on representing an image by a finite-dimensional vector of distances that measure how different the image is from a set of image prototypes. We use the recently introduced Universal Image Distance (UID) \cite{RatsabyChesterIEEE2012} to compare the similarity between an image and a ...

Image Optimization and Prediction [PDF]
arXiv, 2013 Image Processing, Optimization and Prediction of an Image play a key role in Computer Science. Image processing provides a way to analyze and identify an image .Many areas like medical image processing, Satellite images, natural images and artificial images requires lots of analysis and research on optimization.
