Leaf area index (LAI) is one of the key biophysical variables required for crop modeling. Direct LAI measurements are time consuming and difficult to obtain for experimental and commercial fruit orchards. Devices used to estimate LAI have shown considerable errors when compared to ground-truth or destructive measurements, requiring tedious site-specific calibrations. The objective of this study...

At first sight, digital photography which involves taking and sometimes also manipulating, storing, viewing and displaying digital images and floorball, an indoor sport in which players equipped with light-weight sticks try to hit a small ball into the opposing team's goal, have barely anything in common. One is an essentially solitary activity organised around an assortment of relatively hight...

The red eye effect is a well known problem in photography. It is often seen in amateur shots taken with a built-in flash, but the problem is also well known to professional photographers. Red eye is the red reflection of the blood vessels in the retina caused when a strong and sudden light strikes the eye. Red eye is a function of at least three things: • Ambient light level. Low level causes t...

Since the launch of the Hubble Space Telescope there has been widespread popular interest in astronomical imaging. A further series of events, most notably the recent Deep Impact mission have served to fuel further interest in this. In parallel with this there have been a number of events and trends that have increased interest in astronomical photography outside of professional astronomy. Adva...

We propose a level-successive encoding scheme for the compression of continuous tone images. The compressed bit stream is partitioned into individual segments corresponding to successive bits and arranged in order of decreasing significance of the bits. Bit-plane scalability is achieved by recursively partitioning the image into an LSB bit-plane and remaining higher order bits and encoding the ...

While digital panoramic photography taken along travelling routes is very popular, digital panoramic strip maps are virtually nonexistent. In this article, we explore the characteristics of panoramic strip maps and provide an interactive method for their digital creation, focusing on the challenge of straightening curved routes. The resulting software Terrain Bender implements a geometric defor...

media files and almost universal use of email, information sharing is almost instantaneous anywhere in the world. Because many of the procedures performed in dentistry represent established protocols that should be read, learned and then practiced, it becomes clear that photography aids us in teaching or explaining to our patients what we think are common, but to them are complex and mysterious...
