End-to-End Image Patch Quality Assessment for Image/Video With Compression Artifacts

open access: yesIEEE Access, 2020
In this paper, we present an experimental image quality assessment (IQA) method for image/video patches with compression artifacts. Using the High Efficiency Video Coding (HEVC) standard, we create a new database of image patches with compression ...

Image and Video Coding and Formatting [PDF]

open access: yes, 2010
The data acquired by the sensor have to be processed by the coprocessor or the host microprocessor, so both the systems have to share the same communication protocol and data format. Moreover, at the end of the image generation pipeline the image must be coded in a standard format in order to be read by every external device.

Coding of details in very low bit-rate video systems [PDF]

open access: yes, 1994
In this paper, the importance of including small image features at the initial levels of a progressive second generation video coding scheme is presented. It is shown that a number of meaningful small features called details should be coded, even at very

ROI Based Quality Access Control of Compressed Color Image using DWT via Lifting

open access: yesELCVIA Electronic Letters on Computer Vision and Image Analysis, 2009
ROI (Region of Interest) in an image or video signal contains important information and may be used for access control at various qualities using multiresolution analysis (MRA).

Reflectance Prediction Modelling for Residual-Based Hyperspectral Image Coding. [PDF]

open access: yesPLoS ONE, 2016
A Hyperspectral (HS) image provides observational powers beyond human vision capability but represents more than 100 times the data compared to a traditional image.

A video coding system for sign language communication at low bit rates [PDF]

open access: yes, 2004
The ability to communicate remotely through the use of video as promised by wireless networks and already practised over fixed networks, is for deaf people as important as voice telephony is for hearing people. Sign languages are visual-spatial languages

Hierarchical distillation for image compressive sensing reconstruction

open access: yesElectronics Letters, 2021
Compressive sensing (CS) is an effective algorithm for reconstructing images from a small sample of data. CS models combining traditional optimisation‐based CS methods and deep learning have been used to improve image reconstruction performance. However,

YOLOFig detection model development using deep learning

open access: yesIET Image Processing, 2021
The detection of fruit, including accuracy and speed is of great significance for robotic harvesting. Nevertheless, attributes such as illumination variation, occlusion, and so on have made fruit detection a challenging task.

An Adaptive Dictionary Learning Approach for Modeling Dynamical Textures [PDF]

open access: yes, 2013
Video representation is an important and challenging task in the computer vision community. In this paper, we assume that image frames of a moving scene can be modeled as a Linear Dynamical System.
