Analysis of the compression ratio and quality in aerial images
Aviation, 2007 In modern photomap systems, images are stored in centralized storage. Choosing a proper compression format for the storage of an aerial image is an important problem. This paper analyses aerial image compression in popular compression formats.

Robust image and video coding with pyramid vector quantisation [PDF]
, 1999 Most current image and video coding standards use variable length codes to achieve compression, which renders the compressed bitstream very sensitive to channel errors.

Image fusion in the JPEG 2000 domain [PDF]
, 2006 This paper presents a novel approach to image fusion in the JPEG 2000 domain. In this scheme, compressed images are fused without the need for full decompression. The proposed method can be integrated with the existing JPEG 2000 tools.

New patient-controlled abdominal compression method in radiography: radiation dose and image quality
Acta Radiologica Open, 2018 Background The radiation dose for patients can be reduced with many methods and one way is to use abdominal compression. In this study, the radiation dose and image quality for a new patient-controlled compression device were compared with conventional ...

Pediatric Blood &Cancer, EarlyView.ABSTRACT Background Central nervous system (CNS) involvement in childhood acute lymphoblastic leukemia (ALL) is assessed by cell counting and cytomorphology from cerebrospinal fluid (CSF) and is used for treatment stratification worldwide. The ratio of “CNS2” patients in clinical trials ranges from 3% to 40%, with unclear prognostic significance ...

Visual saliency from image features with application to compression
, 2012 Image feature point algorithms and their associated regional de-scriptors can be viewed as primitive detectors of visually-salient information.In this paper, a new method for constructing a visual attention probabilitymap using features is proposed ...

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
