Image-based rendering systems are designed to render a virtual view of a scene based on a set of images and correspondences between these images. This approach is attractive as it does not require explicit scene reconstruction. In this paper we identify that the level of realism of the virtual view is dependent on the camera set-up and the quality of the image analysis and synthesis processes. ...

This paper details a new modular approach to virtual view creation that is designed to work in conjunction with a proposed scalable teleconferencing configuration. This scalable system is configured using building blocks defined as Stereo Camera Analysis Blocks (SCAB). SCABs consist of axe-parallel narrow baseline stereo cameras. These provide design flexibility and improve the image analysis p...

By analyzing vesicle fluids and crusted scabs from 136 persons with suspected monkeypox, we identified 51 cases of monkeypox by PCR, sequenced the hemagglutinin gene, and confirmed 94% of cases by virus culture. PCR demonstrated chickenpox in 61 patients. Coinfection with both viruses was found in 1 additional patient.

Erosive pustular dermatosis of the scalp is a rare inflammatory skin disease that mainly affects older patients and is characterized by the presence of sterile pustules and scabs. Recently, several authors have reported the usefulness of photodynamic therapy in the treatment of this condition. We present the case of a 79-year-old man with skin phototype III and actinic keratosis of the face and...

Blumea balsamifera oil (BBO) is a main extract obtained from Blumea balsamifera (L.) DC (Ainaxiang) leaves, which are widely used as a traditional medicine by the Miao and Li Nations to promote skin trauma or burn injury healing. This study was initiated to investigate the healing efficacy in deep second-degree burn model in rats. The rats were treated by BBO for 21 consecutive days. The rate o...

meatus from which there was a serous discharge. On the external surface of the left side of his neck there was an almost continuous scab of dark yellow colour covering nearly half of it. A little below this, there were a few bullse of about the sizes of a rupee, also a few scabs of smaller size and a few pustules. Below the left axilla there was another scab, about 3" X 4" in size. A little bel...

Smallpox is a viral infection caused by the Variola virus (an Orthopoxvirus) that can affect people of all ages. Smallpox is contagious and has a 30% fatality rate. The infection manifests with a fever, which precedes the development of a progressive rash that occurs all over the body starting in the mouth and on the face. The rash appears as firm, fluid-filled, and singularly dimpled bumps tha...

To review the use of gentian violet 1% (GV) in a long-term care facility for the treatment of small, open wounds and extremity eschars of all sizes and thickness. The records of all the patients receiving topical GV therapy over a period of 1 year, from May 19, 2007 - May 19, 2008 were reviewed. The total sample was 70 patients (38 male, 32 female), average age 65.9 y.o., with 111 wounds (41 pa...

Besides killing many of those who were infected, an attack of smallpox left most of its survivors pockmarked, and it was realized in ancient times that pockmarked persons never caught smallpox again . By accident, it was found that persons who were infected with smallpox via a scratch on the skin suffered a much less severe form of the disease . Long ago, in places in which smallpox had become ...
