Emotions revealed by - Computer software decodes emotions from pictures of faces

Ilse media and the University of Amsterdam have launched, a website which enables the automatic analysis of facial expressions from pictures to reveal someone’s affective state.

By examining key features in pictures of faces such as regions around cheeks, eye-brows and mouth, computer software has been developed which is able to automatically analyze facial expressions to recognize a person’s emotion.

The following emotions can be distinguished: happy, surprised, sad, angry, disgusted and fearful. The same computer software already decoded Mona Lisa’s smile. The result showed that the painting’s famous subject was 83 percent happy and 9 percent disgusted.

The new website allows visitors to upload their pictures. From the uploaded pictures, the website objectively measures the emotion of that person. After emotion recognition, the photos are included in the photo gallery where the explanations of emotions are presented. The software can also be applied to videos.

The new emotion recognition software can be used in a large number of applications such as Internet (video e-mail, MSN, Avatars, Games e.g. Poker), medical applications (detecting mental diseases), commercials and film industry (assessment of a product or commercial), car industry (attention level of the driver), interviews (Detecting the behavior of persons during an interview) and surveillance.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Im Focus: Light-driven atomic rotations excite magnetic waves

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
