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.

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.

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.

Social image quality

SPIE Proceedings, 2011
Current subjective image quality assessments have been developed in the laboratory environments, under controlled-conditions, and are dependent on the participation of limited numbers of observers. In this research, with the help of Web 2.0 and social media technology, a new method for building a subjective image quality metric has been developed where

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.

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.
