researchers have developed a computer that has the ability to decode human
emotions by studying lip pattern.
Karthigayan Muthukaruppan and his colleagues of the Manipal International University in
, have created a system using a genetic algorithm to
correlate irregular ellipse- fitting equations to the shape that the human
mouth takes on while displaying different emotions. The upper and the lower lips of the mouth were identified
as two separate ellipses by the algorithm
. The researchers claim that this
system gets better with each use.
used photos of South-East Asian and Japanese individuals to train the computer
to identify the six common human emotions - happiness, sadness, fear, anger, disgust and surprise
, besides a neutral expression.
There has been a
surge of interest in developing all aspects of human-computer interactions,
especially in the area of human emotion recognition by observing facial
The initial stage application of
an emotion detector might be to help individuals who are mute to interact using
computer-based communication devices, such as voice synthesizers, in a far more
Artificial Intelligence is a 'chip' of the computer science 'block'
. It deals with creating
machines that simulate intelligent human behavior. The term Artificial Intelligence (AI) is also used to describe a trait, a property or a characteristic of
a machine, or the program it contains.
The basis of AI encompasses different
sources of information, from computer science,
physiology and oncology to the abstract components of philosophy. Further
research into the areas of sensory perception, language skills and learning has
amalgamated to create machines that are endowed with the ability to 'think'.
For a very long time, man-like machines such as robots have captivated
man's imagination. His creative genius soared to an all-time high with the invention
of computers. Man was able to create machines that closely resembled and
carried out chores like him, with robotic precision. He invented a slave that did not ask for a break or a
hike in salary! Today, systems are being etched out with the
ability to mimic human speech and thoughts and to perform countless other
chores that were earlier deemed impossible.
The usage of Artificial Intelligence surged
during the nineties and the early part of the twenty first century. This was when greater
emphasis began to be laid on miniscule details; when researchers began
taking a lot more interest in methodical analysis. Besides, AI began to be
associated with several different areas of work.
Some of the traits that these machines today are
capable of exhibiting are learning,
perception, planning, communication, reasoning, knowledge, and the ability to
move/manipulate objects. It is amply used in the
fields of technology, counter terrorism, crisis management, defense, data
mining, and in the realm of medical diagnosis.
The study carried out by the Malaysian researchers has been published in
the International Journal of Artificial
Intelligence and Soft Computing.
