Facial Emotion Recognition Thesis

Identification of facial emotions for the given human face is called facial emotion recognition. Generally, face emotion is helping people to effectively communicate with other people. The prosperity of every communication basically depends upon the accuracy of facial emotion recognition. Uniformity of universal emotions is exposed by many humans to recognize each and every individual’s different expressions. Are you really confused about framing the facial emotion recognition thesis? Then this article is exclusively meant for you!!! Let’s make it worth it!!!

In short, emotions are often called intermediate among people by means of supporting interactions. At the end of this article, you would definitely get all the relevant facts. The article is about to begin hence advising you to pay your kind attention to get the interesting facts and ideas of facial emotion recognition thesis. Come! Let us get into the handout.

Outline of Facial Emotion Recognition

Humans are capable of expressing their feelings in the form of emotions. Faces are the major feature in which emotions are widely expressed. The main usage of emotional expression helps us to recognize the intention of opponent persons.      

The emotions are different in classes such as joy, guilt, contempt, jealousy and this may vary according to the leverage of emotional conditions. In fact, people are supposed to raise or minimize their vocal tones according to the mood they trespass. There are seven emotions that are called basic emotions such as, 

  • Disgust
  • Fear 
  • Sadness
  • Anger
  • Surprise
  • Happiness
  • Neutral

Actually, it is very difficult to examine the emotional conditions expressed in digital platforms like Twitter, Facebook, and so on. 

Facial Emotion Recognition Thesis Writing Guidelines for Research Scholars

Apart from facial expression, emotion recognition is also possible by observing the body gestures of an individual, and the modulation of voice tones would also help us. 

When hard times hits an individual, people tend to express weird and unconventional expressions through the face or body language. Thus it is, very important to recognize the emotion exactly. For this, many of the researchers of our institute and other engineers from all over the world are engaged with researches habitually. 

Here you may get questions like, where we are exactly required facial emotion recognition actually. Is this right? We think we guessed right!!! In fact, we have wrapped the answer in the following passage to make your understanding clear.

Where do we require Facial Emotion Recognition?

Generally, facial emotion recognition thesis ideas is based on widely used to observe individual personalities under several circumstances and it is widely used in the fields of,

  • Driving
  • Hospitals
  • Defense
  • Secured Areas
  • Industries & Retail Shops

In fact, images of human beings are being captured by surveillance cameras and other high-resolution cameras. It simply requires input or even video frames to accurately recognize the users’ emotions. HCI (Human-Computer Interface) is one of the major areas in which we need more assistance with face recognition technology.

The idea behind using face emotion recognition technology in the above-listed areas is to ensure the user’s well-being states. In driving, it exactly recognizes the drivers’ state of mind and helps to avoid accidents whereas in hospitals it is individualizing each and every patient and helps them to survive.  

In fact, the benefits of having face emotion recognition are countless. Better, you can have further explanations in these areas from our academics, if you don’t mind. Here, we would like to illustrate how to recognize facial emotions with the simplest procedures. Come on let us make the session interesting.

How Do We Recognize Facial Emotions?

  • Image Preprocessing
  • Feature Extraction
  • Emotion Classification

These are major steps involved in recognizing human emotions in general. In fact, this can be possible by applying several techniques in each and every process. In short, image or video inputs are preprocessed to extract the features that are helping us to recognize the basic emotions as said earlier.  

Actually, we can exactly recognize the emotions by learning the message’s intensity by observing signals influenced. On the other hand, image preprocessing is one of the major techniques widely used for facial emotion recognition. 

Thus, it improves the quality of the given input (image/video) by pinpointing the area of interest & removing the artifacts in every input. So that image preprocessing is categorized under 3 main techniques. Don’t squeeze your head!!! We are actually going to tell you the same.

Image Preprocessing Techniques for Facial Emotion Recognition
  • ‘Image Filtering’ Techniques
  • ‘Face Detection Techniques
  • ‘Normalization’ Techniques

These are the 3 key techniques being interconnected to the image preprocessing step. As it is the primary stage, it is focusing on enhancing the quality of inputs given. Here, you may shoot questions to us!!! As we are skilled mentors in the industry, we know the student’s mentality. To make your understanding better, we are also going to chit-chat the section with the feature extraction techniques discussions.

Generally, the term feature extraction in emotion recognition refers to the process of converting inputs into other appropriate forms of features. Usually, applications used for facial emotion recognition is using facial features such as mouth, eyes, eyebrows, nose as their sources to proceed further processes.

Feature Extraction Techniques for Facial Emotion Recognition

  • GF- Gabor Filters
  • HWT – Haar Wavelet transforms
  • SVD – Singular Value Decomposition 
  • FFT – Fast Fourier Transform
  • DCT – Discrete Cosine Transform 
  • ICA – Independent Component Analysis
  • PCA – Principal Component Analysis

Itemized above are the various methods used for the feature extraction methods. The main usage of this technique is to make the system computationally very fast by means of minimizing a large amount of data into a lesser amount of feature sets. It is manipulating various technical hitches like, 

  • Pose variations like angles
  • Dissimilarities in facial expressions 
  • Poor illumination conditions

The key idea behind feature extraction is to extract the presented exceptional (unique) features. Face emotion recognition rate is determined by the extracted unique features. Our technical crew is concurrently putting their effort again to make the face extraction techniques in a wow manner. 

Usually, developers are using both filtering and geometric features (2D & 3D) by making use of static image info. For improving system performance, we prefer you, people, to combine the several techniques above listed feature extraction techniques.

Actually, classification is the process of classifying human facial emotions through classifiers. Classifiers in the classification process are concreted with policies & diverse patterns. Non-parametric & parametric classifiers are being suggested by various engineers to plot the issues that arise in facial recognition thesis. In this regard, let us have further discussions on classification techniques in the following passage.

Classification Techniques for Facial Emotion Recognition

  • Deep Learning
    • Decoders & Encoders
    • Convolutional Neural Networks (CNN)
    • Ensemble CNN 
    • Hybrid Algorithms 
  • Statistical Non-machine Learning
    • Linear Discrimination 
    • Euclidean
  • Machine Learning
    • Radial Basis Function
    • Multilayer Perceptron
    • Hidden Markov Model
    • Feed Forward Neural Network

Above itemized are the various classification techniques being connected with the facial emotion recognition as well as they are irreplaceable techniques as this is fulfilling the recognition process by means of consistency. Therefore, they are compressing the false-positive rates arouse by errors.

Optimization techniques are being applied in the areas of features that are extracted. To the end, the classification process is implemented to exactly recognize the particular emotion expressed by an individual.Classification processes can be done effectively by accommodating supervised training which has the capacity to label the data.

An accurate class label is assigned to each and every input by means of classifier training accomplishments. AUs (Action Units) is one of the performances being considered in face emotion recognition like the 7 basic emotions. As of now, we have discussed the foremost fields that are needed before writing a facial emotion recognition thesis.

Now, the academics of our institutes would like to share the famous datasets widely used in the areas of facial emotion recognition for ease of your understanding. In fact, our researchers are well versed in the edges of technology and they are nailing their performance whatever comes into their hands technology-wise. Come, let’s have the next section.
