I wonder how this compares to purely vision-based systems which use nothing but the images themselves for stabilization. Here are some quite old results of stabilization using imag…

"Viewsheds" of any location can be calculated and matched with photographs using "GeoImageViewer", an application I wrote a couple of years ago. Any feature in the photo can be int…

Atmospheric refraction is due to the vertical gradients of atmospheric pressure, temperature, and composition of the atmosphere, all of which are usually not precisely known, and w…

What is definitely wrong in this article is the claim, that only bears eat living prey. Also wolves do that. There are many cases where wolves attacked animals (cows, sheep, deer),…

Combined cycle power plants take heat at 2000°C using a combination of gas and steam turbines. Their conversion efficiency to electric power is 52%, see Wikipedia. This is proven t…

I mentioned GeoImageViewer in a reply above. It contains several algorithms to determine the location of a landscape photo given some control points selected on a map. It is also a…

GeoImageViewer, not an overlay but side-by-side view of photograph and maps. Clicking the image anywhere (not just precalculated pois) shows corresponding location in map and vice-…

Nernst sold the patent in 1902 for 1 Million Mark to AEG, which corresponds to roughly 10 Million EUR today. It was one of the highest valued patents at the time, and is still quit…

A comparison with one of the many SIMD-mathlibraries would have been fairer than with plain libm. Long time ago I wrote such a dual-platform library for the PS3 (cell-processor) an…

There are many projects displaying georeferenced photographs using Leaflet, which usually work via precalculated hotspots in image- and mapview. Here's a project that uses photogra…
