Emotion Recognition using Facial Landmarks, Python, DLib and OpenCV on fer2013 datase 2.2 Landmarks . Landmarks on the face are very crucial and can be used for face detection and recognition. The same landmarks can also be used in the case of expressions. The Dlib library has a 68 facial landmark detector which gives the position of 68 landmarks on the face. Figure 2: Landmarks on face [18 emotions (anger, contempt, disgust, fear, happiness, sadness, and surprise). mean intention is to The overall face extraction from the image is done first using a Viola-Jones cascade object face detector. The Viola-Jones detection framework seeks to identify faces or features o This video demonstrates the working of the facial landmark detection model. The explanation about the working of this model is detailed in my medium article:..
Actually, I used facial landmarks to do emotion recognition and it works well. Now, I am trying to ameliorate the system to do also the identification of the face detected using the facial Landmarks too. So, I am asking if it is applicable to do two types of training on one system (training to do emotion recognition + training to do face. Facial expression for emotion detection has always been an easy task for humans, but achieving the same task with a computer algorithm is quite challenging. With the recent advancement in computer vision and machine learning, it is possible to detect emotions from images. In this paper, we propose a novel technique called facial emotion recognition using convolutional neural networks (FERC)
.e., affective speech and facial expression. For affective speech, the common low-level descriptors including prosodic and spectral audio features (i.e., energy, zero crossing rate, MFCC, LPC, PLP and temporal derivatives) are extracted, whereas a novel visual feature extraction method is proposed. An face emotion recognition system comprises of two step process i.e. face detection (bounded face) in image followed by emotion detection on the detected bounded face. The following two techniques are used for respective mentioned tasks in face recognition system. Haar feature-based cascade classifiers : It detects frontal face in an image well

After previously looking into emotion recognition, I discovered facial landmark detection models. A facial landmarking model locates a specific set of points on a face detected in a given image, usually regardless of the size, location, and position of the face. Using a landmarking model in conjunction with computer vision and ML is an. Human emotions are the universally common mode of interaction. Automated human facial expression identification has its own advantages. In this paper, the author has proposed and developed a methodology to identify facial emotions using facial landmarks and random forest classifier. Firstly, faces are identified in each image using a histogram of oriented gradients with a linear classifier.
