Applying the facial expression recognition algorithm, the developed prototype is capable of processing a sequence of frontal images of moving faces and recognizing the person’s facial expression. The software can be applied to video sequences in realistic situations and can identify the facial expression of a person seated in front of a computer screen. Although still only a prototype, the software is capable of working on a desktop computer or even on a laptop.
Flexibility and adaptability
The system analyses the face of a person sitting in front of a camera connected to a computer running the prototype. The system analyses the person’s face (up to 30 images per second) through several boxes, each “attached” to or focusing on part of the user’s face. These boxes monitor the user’s facial movements until they manage to determine what the facial expression is by comparison with the expressions captured from different people (333 sequences) from the Cohn-Kanade database.
The system’s success rate on the Cohn-Kanade database is 89%. It can work under adverse conditions where ambient lighting, frontal facial movements or camera displacements produce major changes in facial appearance.
This software has a range of applications: advanced human-computer interfaces, improved relations with the e-commerce consumers, and metaverse avatars with an unprecedented capability to relate to the person they represent.
This software can enrich advanced human-computer interfaces because it would enable the construction of avatars that really do simulate a person’s facial expression. This is a really exciting prospect for sectors like the video games industry.
Electronic commerce could also benefit from this technology. During the e-commerce buying process, the computer would be able to identify potential buyers’ gestures, determine whether or not they intend to make a purchase and even gauge how satisfied they are with a product or service by helping to reduce the ambiguities of spoken or written language.
Applied to metaverses like Second Life, this software would also enable the avatars representing system users to act out the feelings of the user captured through facial expressions.
Although there are some facial analysis products on the market, none specifically target the analysis of user facial expressions. Visit the Computational Perception and Robotics Research Group’s website for videos illustrating the algorithm in operation.
Additionally, while most similar systems developed by other researchers focus on just part of expression recognition, the developed prototype does the whole job: 1) locates and monitors the face in the image using an algorithm that works despite changes of illumination or user movement, and 2) classifies the user’s facial expression. Finally, it also incorporates an original algorithm that calculates the likely evolution of the analysed user’s facial expressions.

For the first time, an international team of scientists based in Regensburg, Germany, has recorded the orbitals of single molecules in different charge states in a novel type of microscopy. The research findings are published under the title “Mapping orbital changes upon electron transfer with tunneling microscopy on insulators” in the prestigious journal “Nature”.

Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs. The researchers reported their findings in Nature Communications.
DNA is not only a popular research topic because it contains the blueprint for life – it can also be used to produce tiny components for technical applications.
