Image quality evaluation using image quality ruler and graphical model
2015 IEEE International Conference on Image Processing (ICIP), 2015Quantifying image quality through subjective evaluation is very critical to image quality evaluation. Using the image quality ruler method, an average score per stimulus can be easily obtained in the unit of Just Noticeable Differences (JNDs). However, it requires a large number of subjects, since pure averaging does not consider the different judging ...

Image Quality Evaluation in Security Imaging Systems
IEEE Aerospace and Electronic Systems Magazine, 2007The subjective image quality of image or video information is a crucial item in security imaging systems. During the last five years our lab has tested and verified various approaches to the image compression for security purposes and the evaluation of subjective image quality.

Image quality and noise evaluation
Seventh International Symposium on Signal Processing and Its Applications, 2003. Proceedings., 2003The definition of a 'good image' is subjective and depends on the requirements of a given application Gonzalez, R. C., Woods, R. E. (1992). For example, image quality is highly connected to the process of image sampling and data compression. Noise can be generated and added in during both processes, plus it can also be generated if further processing ...

Crowdsourcing subjective image quality evaluation
2011 18th IEEE International Conference on Image Processing, 2011Subjective tests are generally regarded as the most reliable and definitive methods for assessing image quality. Nevertheless, laboratory studies are time consuming and expensive. Thus, researchers often choose to run informal studies or use objective quality measures, producing results which may not correlate well with human perception.

Image Evaluation Techniques: III. Psychophysical Evaluation Of Image Quality
Journal of Optics, 1973— A comprehensive study on the correlation of physical parameters with thepsychometric judgment values in regard to photographic images has been attemtped. It has been?shown that there is no unique correspondences between the psychometric value and any one ofthe physical parameters that we considred.

Color image database for evaluation of image quality metrics
2008 IEEE 10th Workshop on Multimedia Signal Processing, 2008In this contribution, a new image database for testing full-reference image quality assessment metrics is presented. It is based on 1700 test images (25 reference images, 17 types of distortions for each reference image, 4 levels for each type of distortion).

Image quality evaluation using generalized natural image
SPIE Proceedings, 2008Most image quality metrics are derived from feature values of specified test charts. However, such test charts can explain only a small portion of the comprehensive performances on image quality of imaging systems. Thus, designers of imaging systems need to check every possible type of natural image to verify the performance even if they check every

Evaluation of Stereoscopic Images: Beyond 2D Quality
IEEE Transactions on Broadcasting, 2011Perceived image quality is a standard evaluation concept for 2D imaging systems. When applied to stereoscopic 3D imaging systems, however, it does not incorporate the added value of stereoscopic depth. Higher level evaluation concepts (naturalness and viewing experience) are proposed that are sensitive to both image quality and stereoscopic depth. A 3D

In this paper we describe an overarching framework that allows us to interpret the information from an image. Starting with the imaging device, consideration will be given to the measurement of the quality of the raw data detected by the instrument.

Mission-driven evaluation of imaging system quality
Journal of the Optical Society of America A, 2001Image-quality criteria are usually intended to achieve the best possible image at a given sampling rate, which is ill-suited to applications where the detection of well-defined geometric and radiometric properties of scenes or objects are paramount. The quality criterion developed here for designing observation systems is based on properties of the ...
