Emotion Extractions from Facial Expressions by Using Artificial Intelligence Techniques

We all know what emotions are and how they can influence someone’s decisions. In many fields, emotions play a big role and almost every time they can be seen on someone’s face. It is difficult to read the emotions on somebody’s face when you actually concentrate more on what the person is saying. Not everyone can be a multi-tasking master and pay attention to the body language as well (which by the way, sometimes shows the true feelings of a person). In marketing for example, we can see very clearly the attitude that a customer has over a product just by looking at his face. Let us all agree, life would be way easier if we would be always aware of what a person is truly feeling.

Taking in account all that, researchers Hakan Boz and Utku Kose conducted a study and wrote an article called ’’Emotion Extractions from Facial Expressions by Using Artificial Intelligence Techniques’’. Nowadays, in an era where technology becomes more and more dominant in each and every field, these researchers developed a system that is actually able to identify the emotion of a person based on his facial expression. In detail, the system considered a Cascade Feedforward Artificial Neural Network model trained by a recent optimization algorithm called as Vortex Optimization Algorithm.

The main objective is generally finding the points determining different parts of a face. After determining the related parts of a face, it becomes easier to have idea about i.e. facial expression. On the other hand, it is also important that different genders, different races and even changing sizes of a head – face can affect the way of detecting facial expression. So, it has always been important, especially for researchers working on detecting facial expressions by intelligent systems, to use appropriate types of data. The researchers Boz and Kose applied 3 sets of data, the first set containing 490 photos with genders, and adjusted for 7 emotions, the second set including 810 photos with genders, races, and adjusted for 7 emotions and the third set (the authors’ choices) 100 photos chosen randomly and adjusted for 7 emotions.

In order to train the system, the researchers used Microsoft Kinect 3D infrastructure to gather 3D face points. Microsoft Kinect 3D is a popular system of both hardware and software solutions for effective recognition processes from photos or videos. The results had been positive and the system was able to extract the emotions from different photographs. They used the Vortex Optimization Algorithm. This is an intelligent, Swarm Intelligence based algorithm, which was developed by Kose and Arslan by inspiring from dynamics of vortices in the nature. In detail, the algorithm uses some role-based and evolutionary mechanisms to achieve the optimization solution processes.

In conclusion, the researchers succeeded in developing a system that is effective enough to extract different emotions from photos related to individuals with different gender and even different race. We are all sure that this is the future of technology and soon enough, emotion reading won’t be a secret for the humankind anymore.

    Technology has become more than a phenomenon used for innovation, it is now a science put in the service of making human life easier. If in the past, taking a picture of yourself required a voluminous camera with an obscure chamber, nowadays we have our cameras to ourselves for they are incorporated in our gadgets. Therefore, we take pictures of everything we see – recording reality is just one swipe away and ready in the blink of an eye. However, sometimes is difficult to skim through thousands of photos in order to find a specific one. Nabil M. Hewahi and…

BRAIN: The Interplay among EFL Teachers´ Teaching Experience, Critical Thinking, and Classroom Management

What makes a great teacher? The list is perhaps endless, but many would agree that classroom management is a crucial skill that any teacher needs. Classroom management is a term used to describe the processes by which teachers and schools create and maintain appropriate behavior of students in classroom settings. It is a complex concept as it refers to more than one action. This involves the ability to make each class interesting and thus keeping the students focused, and also dealing with unexpected problems in an appropriate way. When classroom management techniques are applied effectively, the students are active, they participate in class and they are not distracted by other things. They are also encouraged to express their opinions, which enhances their moral and social development.

    Conscience in Language Teaching and its Relationship with Language Proficiency and Emotional Intelligence of EFL Teachers by Sedighe Jalili Kalangestani was published here. Several factors contribute to the efficacy of an English language teacher, among which, language proficiency and emotional intelligence. Yet, there is a newly developed factor which claims to add value to a language teacher. This new factor is called language teaching conscience. Conscience is the sense of right and wrong, which tells us whether what we are doing is morally right or wrong based on particular norms, rules, or religions. Conscientious teachers seem to be more responsible for…

LiBRI: Obsessive Contradictions in ”Pădurea Spânzuraților”

“Pădurea Spânzuraţilor” written by Liviu Rebreanu is a complex novel whose fundamental theme is the inner conflict. The paper Obsessive Contradictions in ”Pădurea spânzuraților” written by Florentina Gabriela Stroe is aimed at highlighting the protagonist’s struggle to regain balance and analyzes the contradictions which occour in his mindset.

Film Adaptation: Forest of the Hanged
Film Adaptation: Forest of the Hanged (1965)

The Romanian writer Liviu Rebreanu published his work in 1922. It was partly inspired by the experience of his brother, an officer in the Austro-Hungarian Army, who was hanged for espionage and desertion during World War I. The criticism of those times were very favorable for the novel and critics like Eugen Lovinescu affirmed that it is the best Romanian psychological novel and also a methodical study powered by precise facts and incidents pushed beyond the rational netting, deep inside the subconscious. No less was said by George Călinescu, who sees the novela as a monography of an agonizing incertitude, in which the main charater illustrates the psychology of the mediocre soul controlled by two different attitudes imposed from the outside.

    Death is a topic of interest for most of us and it is safe to affirm that it generates, depending on temperament and cultural level, completly different views. The theme of death is fundamental in Anton Holban's novels as remaked by Adelina Lascu in her paper. She states that Anton Holban had always advocated for authenticity and for the cult of living, his work being deeply marked by autobiographical elements and themes like love, death, jealousy and a detailed psychological analysis of the inner self. These psychological aspects are uniquely developed in an obsessive manner in each one of his…
