Since usage of digital video is wide spread nowadays, quality considerations have become essential, and industry demand for video quality measurement is rising. This proposal provides a method of perceptual quality assessment in H.264 standard encoder using objective modeling. For this purpose, quality impairments are calculated and a model is developed to compute the perceptual video quality m...

Electroenchephalography (EEG) recordings collected with developmental populations present particular challenges from a data processing perspective. These EEGs have a high degree of artifact contamination and often short recording lengths. As both sample sizes and EEG channel densities increase, traditional processing approaches like manual data rejection are becoming unsustainable. Moreover, su...

This unit describes how to use the genome annotation and curation tools MAKER and MAKER-P to annotate protein-coding and noncoding RNA genes in newly assembled genomes, update/combine legacy annotations in light of new evidence, add quality metrics to annotations from other pipelines, and map existing annotations to a new assembly. MAKER and MAKER-P can rapidly annotate genomes of any size, and...

This study aims to complement existing fish-based assessment approaches by classifying European lampreys and fish species according their probability of occurrence in six different longitudinal river regions five types floodplain water bodies under unimpaired conditions. The main objective was provide for the first time harmonized traits fishes both lateral dimensions systems a Fish Region Inde...

degradation model was introduced as an instrument of environmental impact assessment (eia) in iran. several methods are introduced in rapid environmental assessment, but none of them have evaluated landscape level. thus, the main objective of this research is to introduce a new spatial method for eia by using landscape metrics. a benefit of rapid assessment by using ecological landscape metrics...

This paper describes the issues addressed when developing and implementing the IBM reuse metrics and return on investment model [25]. Recognizing the potential benefits of reuse has proven instrumental in inserting reuse in the IBM programming process. However, many issues arise in a large organization when implementing metrics due to the diversity in computer languages, environments, and cultu...

OBJECTIVES To identify the critical dimensions of hospital Chief Executive Officers' (CEOs) involvement in a quality and safety and to offer practical guidance to assist CEOs to fulfil their leadership role in quality improvement (QI). DESIGN Qualitative interview study. SETTING 20 organisations participating in the main phase of the Safer Patients Initiative (SPI) programme across the UK. ...

PURPOSE To determine the precision (repeatability) of several methods of calculating refraction from higher-order wavefront aberration data and to compare these wavefront refractions with lower-order (LO) wavefront refraction, subjective refraction, and autorefraction. METHODS Four clinicians refracted 16 normal participants aged 23.6 +/- 1.2 years, 69% female with an average spherical equiva...

Second in a two-part series comparing measurement techniques for the assessment of basic image quality metrics in digital radiography, in this paper we focus on the measurement of the image noise power spectrum (NPS). Three methods were considered: (1) a method published by Dobbins et al. [Med. Phys. 22, 1581-1593 (1995)], (2) a method published by Samei et al. [Med. Phys. 30, 608-622 (2003)], ...
