We present an algorithm to estimate the 3D pose (location and orientation) of a previously unseen face from low-quality range images. The algorithm generates many pose candidates from a signature to find the nose tip based on local shape, and then evaluates each candidate by computing an error function. Our algorithm incorporates 2D and 3D cues to make the system robust to low-quality range ima...

BACKGROUND Osteoarthritis is the most common chronic disease in the UK, with greater prevalence in women, older people, and those with poorer socioeconomic status. Effective treatments are available, yet little is known about the quality of primary care for this disabling condition. AIM To measure the recorded quality of primary care for osteoarthritis, and assess variations by patient and/or...

Background: A challenge of metabolomics is data processing the enormous amount of information generated by sophisticated analytical techniques. The raw data of an untargeted metabolomic experiment are composited with unwanted biological and technical variations that confound the biological variations of interest. The art of data normalisation to offset these variations and/or eliminate experime...

Facial recognition systems have their accuracy based on the intra-class variations between two stages in particular, enrollment and identification. These intra-class variations are affected by the lighting conditions with other reasons such as, facial expressions, pose, occlusion, poor sensor quality, and illumination quality. To identify a face or an object with accuracy, all such errors need ...

A high-quality reference genome is critical for understanding genome structure, genetic variation and evolution of an organism. Here we report the de novo assembly of an indica rice genome Shuhui498 (R498) through the integration of single-molecule sequencing and mapping data, genetic map and fosmid sequence tags. The 390.3 Mb assembly is estimated to cover more than 99% of the R498 genome and ...

background blastocystis is a common protozoan parasite in mammals, birds, amphibians,reptiles, fish, arthropods, and annelids. this parasite has some subtypes, which pathogenicity status of them still remained controversial. some of blastocystis subtypes are potentially pathogenic to human. objectives this study has identified the blastocystis hominis subtypes and their prevalence rates in hama...

One current approach to quality control in DNA array manufacturing is to synthesize a small set of test probes that detect variation in the manufacturing process. These fidelity probes consist of identical copies of the same probe, but they are deliberately manufactured using different steps of the manufacturing process. A known target is hybridized to these probes, and those hybridization resu...

Variations research is one important strategy in the quality management movement designed to improve the quality of health care and to control costs. Information systems are being utilized in variations research to provide an array of potential variables, to provide measures of the variability inherent in these variables, and to assist with the study of the linkages of patient and provider char...
