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.

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 ...

Quality of Images

2016
An image is the result of the optical imaging process which maps physical scene properties onto a two-dimensional luminance distribution; it encodes important and useful information about the geometry of the scene and the properties of the objects located within this scene [339, 611, 687].

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 in image classification: Design and construction of an image quality database

Computers & Chemical Engineering, 2009
Image quality affects automated classification of images from process camera monitors. The objective of this work was to obtain a database of reference images that could enable automated, customized image quality modification to improve classification of new images.

Image Contrast and Quality [PDF]

open access: possible, 1990
This laboratory demonstrates: (1) the two major types of contrast in SEM images, known as atomic number contrast and topographic contrast, (2) the factors affecting the quality of the image and how they ultimately limit the image resolution, and (3) the effects of electronic signal processing on the visibility of features in the image. More details and

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.

From image quality to patch quality: An Image-Patch Model for No-Reference image quality assessment

2017 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2017
Supervised learning is gradually used for image quality assessment (IQA). For the patch-based methods, the ‘ground truth’ quality of patches is essential for training, but in practice it's easy to obtain the ground truth quality of images rather than patches.

A Novel Image Quality Index for Image Quality Assessment

2013
Image quality assessment (IQA) is provided as computational models to measure the quality of images in perceptually consistent manner. In this paper, a novel image quality index with highlighting shape of histogram of the image targeted is introduced to assess image qualities.
