An Image Lossless Compression Patent

open access: yesComputer and Information Science, 2010
The present general lossless compression algorithm is not effective for the compression effect of JPEG files. In this article, the lossless compression method combining the shuffling algorithm with the lossless compression algorithm and a new shuffling algorithm are proposed, and this new algorithm could compresses the JPEG files without losses, and ...

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.

HYBRID COMPRESSION OF CERVICAL IMAGES BY SEGMENTING NUCLEI-CYTOPLASM [PDF]

open access: yesICTACT Journal on Image and Video Processing, 2012
A hybrid image compression method is proposed by which the Nuclei-Cytoplasm of the image is completely restorable and the background part of the image is restorable with insignificant loss.

A contrast-sensitive reversible visible image watermarking technique [PDF]

open access: yes, 2009
A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme is proposed to satisfy the applications, in which the visible watermark is expected to combat copyright piracy but can be removed to losslessly recover the ...

A Reversible Data Hiding Method in Encrypted Images for Controlling Trade-Off between Hiding Capacity and Compression Efficiency

open access: yesJournal of Imaging, 2021
In this paper, we propose a new framework for reversible data hiding in encrypted images, where both the hiding capacity and lossless compression efficiency are flexibly controlled.

Two‐Dimensional Isotropic Spatial Differentiation Through Complete Polarization Control

open access: yesAdvanced Optical Materials, EarlyView.
This work enables two‐dimensional isotropic spatial differentiation at planar interfaces over a wide range of incident angles by extending the output polarization from linear to elliptical. The choice of incident angle can be used to balance broader spectral response at low angles and higher edge‐detection efficiency at larger angles.
