Modern digital technology and the availability of increasingly powerful image processing tools can easily manipulate the digital images without leaving obvious visual traces of having been tampered, so there is an urgent need to identify the authenticity of images. In the fields such as forensics, medical imaging, e-commerce, and industrial photography, authenticity and integrity of digital ima...

Rapid, reliable and objective estimations of Leaf Area Index (LAI) are essential for numerous studies of the atmosphere, as LAI is very often a critical parameter in process-based models of vegetation canopy response to global environmental change. This paper compiles current knowledge concerning the use of direct and indirect methods for LAI determination. The emphasis will be on techniques, t...

We present efforts to explore the relatively underdeveloped area of digital photo display. Using examples from two empirical studies with family homes, we develop our results around three broad themes related to the display of photos and their arrangement. The first theme highlights the collaborative as well as individual work that goes into preparing photos for display. The second attends to t...

Public displays of photographs are a common sight in community spaces, yet while much attention has been given recently to the use of digital photography in the home, the community domain remains underexplored.
