Quality analysis of pansharpened images
IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004In general, image fusion or sharpening is of great importance to various remote sensing and mapping applications, where the spatial information from a "high-resolution" image is merged with the radiometric information from a "low-resolution" image.

Quality of, and Quality Control of, Urolithiasis Analysis
1976Good quality chemical analysis of renal stones is essential if clinicians are to base treatment on the chemical composition of the stones, and if high quality research is to be carried out. During the last 25 years many surveys have been made on the quality of clinical chemical analyses, and quality control techniques have been applied to many of the ...

Quality Aspects of TMA Analysis
2010The quality of a TMA experiment can only be as good as the worst step in the entire process. Making and analyzing of tissue microarrays (TMAs) is a complex process involving tissue sample acquisition and preparation, expert histological diagnosis, long-term collection of clinical data, development of suitable laboratory protocols, the microscopic ...

Quality adjusted survival analysis
Statistics in Medicine, 1990AbstractWe present a technique, quality adjusted survival analysis, for the analysis of controlled trials where patients may experience several health states which differ in their quality of life. When the data are censored, a survival analysis of the quality adjusted life years achieved may involve informative censoring, and produce biased estimates ...

Analysis of Statistical Data Quality
2014 Seventh International Joint Conference on Computational Sciences and Optimization, 2014Statistical data quality refers to the accuracy of the statistics. Accurate and reliable statistics is the important basis for scientific decision and scientific management. Aiming at the phenomenon of some statistical dishonesty problem shown in this paper the causes of this phenomenon are briefly analyzed, and we put forward the measures to improve ...

Fingerprint quality and validity analysis
Proceedings. International Conference on Image Processing, 2003Discusses methods to estimate the quality as well as validity of a fingerprint image. Orientation certainty is used to certify the localized texture pattern of the fingerprint images while ridge to valley structure is analyzed to detect invalid images. Global uniformity and continuity ensures that the image is valid as a whole.

The Quality Analysis of Image Reproduction
Journal of Imaging Science and Technology, 2000The objective of image reproduction is, as used here, to reproduce visual information that is available in the original image. Undoubtedly, the colors of the individual pixels contain a huge amount of visual information and therefore the quality of the image reproduction is typically studied in terms of the quality of the color reproduction determined ...

Criteria for the analysis of scientific quality
Scientometrics, 1995One of the major questions in science research is addressed in detail, that is the problem of evaluation of research work both by objective characterization, accessible to proof, and by adequate characterization, referring to the content and cognitive level of the work under investigation. A short discussion of established methods by science indicators
