The Science Behind Music: How Dıgial Signal Processing Powers Our Favorite Tunes

By: 
Dr. Ibrahim Atakan KUBİLAY

What if we lived in a world without music?  It’s utterly unthinkable. Music has long been an important part of human life.  Researchers found human remain alongside flutes made from animal bones dating more than 40,000 years ago1.  In ancient Greek mythology, muses were goddesses or water nymphs, inspiring humans in the fields of art and science, and spurring incredible developments2.

How MRIs are Changing How Society Looks at your Brain

By: 
Dale Mugler

Have you had an experience in an MRI scanner? Chances are you have or know someone who has. Magnetic Resonance Imaging produces detailed pictures of soft tissue in the human body – but, unlike many other techniques, it does not require any radiation.

A New Era in Human Computer Interaction: Facial Expression Recognition

By: 
Cigdem Turan, Ph.D. Candidate at Hong Kong PolyU

How would you feel if electronic devices could recognize your emotion and take actions based on it? They could cheer you up with a joke when you are sad. They’d recognize sleepiness while you were driving, and help you understand if a person was in real pain or just claiming to be. They could differentiate the Duchenne smile from the forced one or detect depression using facial muscle movements. These applications aren’t promises of the future: they’re possible today with recent developments in signal processing and machine learning algorithms.

A ‘Scholar in the Making’: Student Member Sean Young reflects on his time with the IEEE Signal Processing Society

By: 
Jessica Perry, SPS

A self-proclaimed “scholar in the making,” SPS Student Member Sean Young credits his growth in the field to his time with the Society. From connecting with like-minded individuals to attending conferences, Sean recognizes the impact it’s had on his career and his research. To kick off Engineers Week (running from February 19-25, 2017), we spoke with Sean about his journey with SPS, his future in the field, and what advice he’d offer to those just getting started.

Signal Processing for Social Good

By: 
Kush R. Varshney

Kush R. Varshney, research staff member and manager in the Data Science Group at the IBM Thomas J. Watson Research Center.
Communication, speech processing, seismology and radar are well-known applications of signal processing that contribute to the betterment of humanity. But is there a more direct way that signal and information processing can reduce poverty, hunger, inequality, injustice, ill health and other causes of human suffering?

Sensors and Sensibility

By: 
Vladimir Pavlovic, Senior Staff Engineer at Sierra Wireless

Depending on who do you ask, we have five, six, or even twenty-one senses. Besides touch, vision, hearing, smell and taste, which we are taught about in kindergarten, we have senses of balance, hot and cold, pain, magnetic orientation (although very weak and close to nonexistent), position of our limbs relative to other parts of the body (can you touch your nose while eyes shut?), and more. If you hoped the sixth sense has anything to do with paranormal, I have to disappoint you.

A Visual Innovator and Entrepreneur, Steve Chen Sits at the Heart of Silicon Valley

By: 
Jessica Perry, IEEE Signal Processing Society

Humans have been fascinated with light and optics since prehistoric times, when the first “camera” was used to project upside down images onto cave walls. IEEE recently presented the world’s first Visual Innovation Award to showcase innovations that made great impact on human experiences with visual technology or are anticipated to do so in the near future.

How Biometric Authentication Poses New Challenges to Our Security and Privacy

By: 
Nasir Memon

Nasir Memon, Computer Science and Engineering NYU Tandon School of Engineering
The use of biometric data – an individual’s measurable physical and behavioral characteristics – isn’t new. Government and law enforcement agencies have long used it. The FBI has been building a biometric recognition database; the Department of Homeland Security is sharing its iris and facial recognition of foreigners with the FBI.

No Need for Speed: More innovation needed before adopting automated vehicles

By: 
Wade Trappe

This article originally appeared on Robotic Tips.
We spend a considerable amount of time driving - to work and home, for recreation and travel. Envisioning a completely autonomous world, we’ll be able to rent a vehicle pre-programmed to take us to a specified destination. Drivers will be able to disengage to read the newspaper while the car carries out their commute and seamlessly coordinates to ensure the safety of its passengers.
