Quality-aware images

IEEE Transactions on Image Processing, 2006
We propose the concept of quality-aware image, in which certain extracted features of the original (high-quality) image are embedded into the image data as invisible hidden messages. When a distorted version of such an image is received, users can decode the hidden messages and use them to provide an objective measure of the quality of the distorted ...

Xeromammographic image quality

Medical Physics, 1980
Xeroradiography is a diagnostic modality whose image‐forming properties are fundamentally different from those of the conventional silver halide process. In this work, the xeromammographic process, representing the low‐contrast limit of xeroradiography, is analyzed in detail.

Image quality and image resolution

2013 Seventh International Conference on Sensing Technology (ICST), 2013
13 years after the introduction of the first digital airborne mapping camera in the ISPRS conference 2000 in Amsterdam, several digital cameras with more than 100 MPixels per image have been made available. They are now well established in the market and have replaced the analogue mapping cameras.

Quantifying image quality

Clinical Physics and Physiological Measurement, 1990
The measurement of image quality is an essential stage in the evaluation of imaging techniques. Yet there is no accepted way of quantitatively assessing image quality. Current theories suggest that the quality of the raw data acquired by the device can be assessed independently from that of the displayed image.

Evaporographic Image Quality

Applied Optics, 1967
The steps in reproducing evaporograph images are discussed. An analysis of signal and noise is given for different stages of the evaporograph process. The factors which limit the threshold sensitivity and resolving power of the evaporograph transducer are determined.

Underwater image quality assessment

Journal of the Optical Society of America A, 2023
To obtain high-visual-quality underwater images by image post-processing, many underwater image restoration and enhancement methods have been proposed. Underwater image quality assessment (UIQA) methods have been developed to compare these restoration and enhancement methods.

Digital Radiography Image Quality: Image Acquisition

Journal of the American College of Radiology, 2007
This article on digital radiography image acquisition is the first of two articles written as part of an intersociety effort to establish image quality standards for digital and computed radiography. The topic of the other paper is digital radiography image processing and display.
