1. 1. Vision based facial emotion detection using deep convolutional neural networks

   University essay from Mälardalens högskola/Akademin för innovation, design och teknik

   Author : Fredrik Julin; [2019]
   Keywords : Computer vision; Deep learning; Convolutional neural network; CNN; Neural network; Machine learning; emotion detection; facial expression recognition; real-time; face detection;

   Abstract : Emotion detection, also known as Facial expression recognition, is the art of mapping an emotion to some sort of input data taken from a human. This is a powerful tool to extract valuable information from individuals which can be used as data for many different purposes, ranging from medical conditions such as depression to customer feedback.

3. 2. Detecting Sitting People : Image classification on a small device to detect sitting people in real-time video

   University essay from Mittuniversitetet/Avdelningen för informationssystem och -teknologi

   Author : Jonathan Olsson; [2017]
   Keywords : OpenCV; image-processing; AdaBoost; Viola-Jones; Raspberry Pi; Haar cascades; Haar features;

   Abstract : The area of computer vision has been making big improvements in the latest decades, equally so has the area of electronics and small computers improved. These areas together have made it more available to build small, standalone systems for object detection in live video. This project's main objective is to examine whether a small device, e.g. READ MORE

4. 3. Human Attention : The possibility of measuring human attention using OpenCV and the Viola-Jones face detection algorithm

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Jonatan Cöster; Michael Ohlsson; [2015]
   Keywords : ;

   Abstract : The question of whether an audience is focused and attentive can be of great importance. Research shows that a main concern during lectures is the varying level of attention from the students. Getting real time feedback on the students attention could give the lecturer an insight into what can be improved in terms of the material being presented. READ MORE

5. 4. Measuring Student Attention with Face Detection: : Viola-Jones versus Multi-Block Local Binary Pattern using OpenCV

   University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

   Author : Josefine Eriksson; Lindelöf Anna; [2015]
   Keywords : ;

   Abstract : The purpose of this study is to discuss and attempt to approach an answer to the question of how face detection could be used to measure attention in a lecture hall.The conclusion might help further studies in using face detection to provide teachers with tools which can be used to improve learning during lectures.

6. 5. Face Tracking Using Optical Flow : Real-Time Optical Flow Enhanced AdaBoost Cascade Face Tracker

   University essay from Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

   Author : Andreas Ranftl; [2014]
   Keywords : Face; Tracking; Likelihood Map; Optical Flow; Viola-Jones; AdaBoost Cascade Classifier; OpenCV; C ; MEX; Boston Head Tracking Database;

   Abstract : This master thesis deals with real-time algorithms and techniques for face detection and facetracking in videos. A new approach is presented where optical flow information is incorporatedinto the Viola-Jones face detection algorithm, allowing the algorithm to update the expectedposition of detected faces in the next frame.
