The relationship between compression force, image quality and radiation dose in mammography
South African Journal of Radiology, 2009 Background. Mammography aims to obtain mammograms of best possible image quality with least possible radiation dose.1 Theoretically, an increase in breast compression gives a reduction in thickness, without changing the density, resulting in improved ...

SAR image compression using optronic processing
The Journal of Engineering, 2019 SAR image compression is important for space-borne SAR systems. Many compression methods were proposed, conventional methods were based on digital processing. Traditional methods are much computation and storage consumption. A novel SAR image compression

Imaging via Compressive Sampling [Introduction to compressive sampling and recovery via convex programming] [PDF]
, 2008 There is an extensive body of literature on image compression, but the central concept is straightforward: we transform the image into an appropriate basis and then code only the important expansion coefficients.

Compressive Optical Image Encryption [PDF]
Scientific Reports, 2015 AbstractAn optical image encryption technique based on compressive sensing using fully optical means has been proposed. An object image is first encrypted to a white-sense stationary noise pattern using a double random phase encoding (DRPE) method in a Mach-Zehnder interferometer.

JPEG compression history detection based on detail deviation
Mathematical Biosciences and Engineering, 2019 The authenticity of the image is crucial to many cases. The efficient detection of the JPEG compression history of bitmap image could reveal the possibility of tampering on the image.
