Review of Very Low Bitrate Image Compression Techniques

open access: yesShuju Caiji Yu Chuli
Image is one of the important ways to obtain information. With the increasing demand of image transmission and storage, especially in bandwidth limited or cloud storage situations, compressing images at extremely low bitrates is of great significance for

Efficient Lossy Compression for Compressive Sensing Acquisition of Images in Compressive Sensing Imaging Systems

open access: yesSensors, 2014
Compressive Sensing Imaging (CSI) is a new framework for image acquisition, which enables the simultaneous acquisition and compression of a scene. Since the characteristics of Compressive Sensing (CS) acquisition are very different from traditional image

Lossy Compression of Multichannel Remote Sensing Images with Quality Control

open access: yesRemote Sensing, 2020
Lossy compression is widely used to decrease the size of multichannel remote sensing data. Alongside this positive effect, lossy compression may lead to a negative outcome as making worse image classification.

On strange images with application to lossy image compression

open access: yesРадіоелектронні і комп'ютерні системи, 2022
Single and three-channel images are widely used in numerous applications. Due to the increasing volume of such data, they must be compressed where lossy compression offers more opportunities.

ROI coding of volumetric medical images with application to visualisation [PDF]

open access: yes, 2003
This paper presents region of interest (ROI) coding of volumetric medical images with the region itself being three dimensional. An extension to 3D-SPIHT which allows 3D ROI coding is proposed.

The fidelity of compressed and interpolated medical images

open access: yesTechnical Transactions, 2020
Due to the amount of medical image data being produced and transferred over networks, employing lossy compression has been accepted by worldwide regulatory bodies. As expected, increasing the degree of compression leads to decreasing image fidelity.

Iris Image Compression Using Deep Convolutional Neural Networks

open access: yesSensors, 2022
Compression is a way of encoding digital data so that it takes up less storage and requires less network bandwidth to be transmitted, which is currently an imperative need for iris recognition systems due to the large amounts of data involved, while deep

Colour volumetric compression for realistic view synthesis applications [PDF]

open access: yes, 2007
The colour volumetric data which is constructed from a set of multi-view images is capable of providing realistic immersive experience. However it is not widely applicable due to its manifold increase in bandwidth.

Quality criteria benchmark for hyperspectral imagery [PDF]

open access: yes, 2005
Hyperspectral data appear to be of a growing interest over the past few years. However, applications for hyperspectral data are still in their infancy as handling the significant size of the data presents a challenge for the user community.
