MP3 players and digital cameras fill home computers with a data flood of images and music. The sector association BITKOM estimated that the number of music downloads in 2008 would exceed 38 million in Germany. Until now, anyone wishing to maintain an overview of their favorite music and photos had to laboriously assign keywords to everything using cumbersome administration software.
A new approach is to sort the data according to moods. The mood player developed by the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau compiles musical slide shows to match how the user feels at the time. From euphoric, relaxed and melancholic to vigorous. The software, which is based on the GenreID music analysis tool, trains the PC to recognize different musical characteristics. Images that suit the mood are automatically added to the play list and shown at a speed that matches the tempo of the music.
For this purpose, the mood player classifies the media in real time and makes the acquired information available in a database. The mood of the images is analyzed on the basis of several distinguishing parameters, including brightness, contrast, edges, colors, textures, layout and shape. Warm colors, for instance, represent friendliness and strong emotions, whereas cold colors have a more calming, distanced and melancholic effect.
Factors such as saturation, brightness, structures and the combination and arrangement of different colors are decisive in the image analysis. The pieces of music too are sorted according to mood parameters, such as volume, tone, melody, rhythm, instruments and vocals – automatically, without the need for tedious cataloging.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
