OBJECTIVE Our aims were to: establish the clinical significance of ultrasound, thermography, photography and subepidermal moisture (SEM) measurement; determine the accuracy of ultrasound, thermography, photography and SEM measurement in detecting skin/tissue damage; determine the relative accuracy of one of these assessment methods over another; make recommendations for practice pertaining to a...

We look at how a seemingly small change in the photographic process—capturing a focal stack at the press of a button, instead of a single photo—can boost significantly the optical performance of a conventional camera. By generalizing the familiar photographic concepts of “depth of field” and “exposure time” to the case of focal stacks, we show that focal stack photography has two performance ad...

Aerial photogrammetry is one of the main methods obtaining geospatial information. After entering the 21st century, aerial photogrammetry technology has fully entered the digital age, and the quality of digital aerial photography results will directly affect the quality and accuracy of results of surveying and mapping .Therefore, it is necessary to inspect the quality of digital aerial photogra...

OBJECTIVES To provide the practicing surgeon with data to make an informed economic decision regarding conversion from analog to digital photography. METHODS A cost analysis of photography based on 35-mm vs digital platforms (low-, medium-, and high-cost hardware). RESULTS Break-even thresholds for the investment in a digital platform of low, medium, and high costs were 3674, 15,789, and 34...
