Abstract and Figures

Facial Expression Recognition has become the preliminary research area due to its importance in human-computer interaction. Facial Expressions conveys the major part of information so it has vast applications in various fields. Many techniques have been developed in the literature but there is still a need to make the current expression recognition methods efficient. This paper represents proposed framework for face detection and recognizing six universal facial expressions such as happy, anger, disgust, fear, surprise, sad along with neutral face. Viola-Jones method and Face Landmark Detection method are used for face detection. Histogram of oriented gradients is used for feature extraction due to its superiority over other methods. To reduce the dimensionality of features Principal Component Analysis is used so that the maximum variation is preserved. Canberra distance classifier is used for classifying the expressions into different emotions. The proposed method is applied on Japanese Female Facial Expression Database and have evaluated that the proposed method outperforms many state-of-the-art techniques.

  • Nov 2023
The K-Means Clustering algorithm is commonly used by researchers in grouping data. The main problem in this study was that it has yet to be discovered how optimal the grouping with variations in distance calculations is in K-Means Clustering. The purpose of this research was to compare distance calculation methods with K-Means such as Euclidean Distance, Canberra Distance, Chebychev Distance, Cosine Similarity, Dynamic TimeWarping Distance, Jaccard Similarity, and Manhattan Distance to find out how optimal the distance calculation is in the K-Means method. The best distancecalculation was determined from the smallest Davies Bouldin Index value. This research aimed to find optimal clusters using the K-Means Clustering algorithm with seven distance calculations based on types of numerical measures. This research method compared distance calculation methods in the K-Means algorithm, such as Euclidean Distance, Canberra Distance, Chebychev Distance, Cosine Smilirity, Dynamic Time Warping Distance, Jaccard Smilirity and Manhattan Distance to find out how optimal the distance calculation is in the K-Means method. Determining the best distance calculation can be seen from the smallest Davies Bouldin Index value. The data used in this study was on cosmetic sales at Devi Cosmetics, consisting of cosmetics sales from January to April 2022 with 56 product items. The result of this study was a comparison of numerical measures in the K-Means Clustering algorithm. The optimal cluster was calculating the Euclidean distance with a total of 9 clusters with a DBI value of 0.224. In comparison, the best average DBI value was the calculation of the Euclidean Distance with an average DBI value of 0.265.

Autonomous Traffic System for Emergency Vehicles
Article
Full-text available
  • Feb 2022
An emergency can occur at any time. To overcome that emergency efficiently, we require seamless movement on the road to approach the destination within a limited time by using an Emergency Vehicle (EV). This paper proposes an emergency vehicle management solution (EVMS) to determine an efficient vehicle-passing sequence that allows the EV to cross a junction without any delay. The proposed system passes the EV and minimally affects the travel times of other vehicles on the junction. In the presence of an EV in the communication range, the proposed system prioritizes the EV by creating space for it in the lane adjacent to the shoulder lane. The shoulder lane is a lane that cyclists and motorcyclists will use in normal situations. However, when an EV enters the communication range, traffic from the adjacent lane will move to the shoulder lane. As the number of vehicles on the road increases rapidly, crossing the EV in the shortest possible time is crucial. The EVMS and algorithms are presented in this study to find the optimal vehicle sequence that gives EVs the highest priority. The proposed solution uses cutting-edge technologies (IoT Sensors, GPS, 5G, and Cloud computing) to collect and pass EVs’ information to the Roadside Units (RSU). The proposed solution was evaluated through mathematical modeling. The results show that the EVMS can reduce the travel times of EVs significantly without causing any performance degradation of normal vehicles.

Fusion of multi representation and multi descriptors for facial expression recognition
Article
Full-text available
  • Feb 2021
Facial Expression Recognition has become vital for efficient Human Computer Interaction. In this paper, we propose effective facial expression recognition approachfor recognizing six basic facial expressions. Our approach consists of three main phases which are: (1) face detection and pre-processing, (2) features extraction and (3) facial expression classification. The face pre-processing phase is performed using the facial landmarks. After the face is aligned and cropped, facial regions of interest (eyes, nose and mouth) are detected. In the features extraction phase, we used Histogram of oriented gradients (HOG), Local Binary Pattern (LBP) and the fusion of the two features. For the last step, Support Vector Machine (SVM) is used to recognize the facial expression. To evaluate the performance of our approach, we used three popular datasets which are The Extended Cohn-Kanade (CK+), The Japanese Female Facial Expression (JAFFE) and Oulu-CASIA NIR-VIS dataset (CASIA), In addition, 10 folds cross-validation scheme is used to evaluate the performance of our approach. Our proposed fusion of multi representations and multi descriptors achieves better or competitive performance compared with the state-of-the-art methods. The accuracies of our approach are 99.18%, 95.77% and 99.09% for CK+, JAFFE and CASIA, respectively. The results prove the efficiency of our approach although the challenging conditions from one dataset to another.

A multi‐scale feature fusion convolutional neural network for facial expression recognition
Article
Full-text available
  • Dec 2023
  • EXPERT SYST
This paper designs a new facial Expression recognition network called a multi‐scale feature Fusion Convolutional neural Network (EFCN). This network is proposed to solve two problems in the facial expression recognition task. First, there are many commonalities between faces of different expression categories, and the recognition task cannot be precisely performed when the commonality is greater than the individuality. Secondly, facial detail features have a significant impact on the final results of expression recognition, while the image detail features extracted by traditional convolutional neural networks are not sufficient. In order to address the above issues, the feature enhancement network (FEN) and the detail information enhancement module (DEM) are designed. The FEN fuses deep and shallow features. Accordingly, the feature map contains richer information, making it easy to identify the samples. The DEM extracts and fuses the features passed by the backbone network with multi‐scale features to enhance the network's ability to extract features from small regions of the face. We validated the proposed method on three datasets, RAF‐DB, CK+, and JAFFE, and achieved 84.50%, 97.86%, and 91.05% accuracy, respectively, and the experimental results showed the effectiveness of the proposed method in this paper. For example, on the JAFFE dataset, the recognition accuracy of this method surpasses the MLT method by 1.87%.

A State of the Art Technology with Machine Intelligence in Human Emotion Recognition
Article
  • Jul 2021
Emotion plays a significant role in human understanding and generally connected with rational decision making, attitudes, human activity, and human intelligence. To create realistic emotional relations between human beings and machines, the research community’s increasing interests need reliable and deployable solutions to recognize human emotional conditions. Automatic emotion detection is one of the main obstacles in providing innovative methods for more comfortable and more objective diagnosis, communication and analysis. Hence in this paper, an Artificial intelligence-assisted emotion prediction model (AIEPM) has been proposed to evaluate the probability of digital representation, identification and estimation of feelings, their state-of-the-art methods and primary research guidance. The proposed AIEPM analyses the effect on multimodal detection of emotional models. This paper presents emerging works based on language, sound, image, film, and physiological signals using current methods such as machine intelligence for recognizing human emotion. The proposed emphasis on this cutting-edge analysis reflects elements like the form and presentation of emotional stimulation, the sample’s scale. The numerical outcome suggested AIEPM, according to age, behaviour classification according to age (95.2%), emotions state recognition high probability in satisfaction compared to the proposed method, accuracy ratio (89.6%), performance ratio (94.5%) and recognition outcomes of existing and proposed work (98.2%) compared to other existing approaches improve behaviour classification.

Facial Emotion Recognition Using Asymmetric Pyramidal Networks With Gradient Centralization
Article
Full-text available
  • Jan 2021
Facial expression recognition (FER) is a promising but challenging area of Computer Vision (CV). Many researchers have devoted significant resources to exploring FER in recent years, but an impediment remains: classifiers perform well on fine resolution images but have difficulty recognizing in-the-wild human emotional states. In order to solve the aforementioned issue, we introduced three novel designs and implemented them in neural networks. More specifically, we utilized an asymmetric pyramidal network (APNet) and employed multi-scale kernels instead of identical size kernels. In addition, square kernels were replaced by a sequence of square, horizontal, and vertical convolutions. This structure can increase the description ability of convolutional neural networks (CNN) and transfer multi-scale features between different layers. Additionally, when training CNN, we adopted stochastic gradient descent with gradient centralization (SGDGC) where it centralizes gradients to have zero mean and makes the training process more efficient and stable. To verify the effectiveness of APNet with SGDGC, we used three of the most popular in-the-wild emotion datasets, FER-2013, CK+, and JAFFE, for our experiments. The results of our experiment and comparisons with state-of-the-art designs from others demonstrate that our method outperforms all the single model methods and has comparable performance with model fusion methods.

Efficient Face and Facial Expression Recognition Model
Conference Paper
Full-text available
  • Aug 2016
This paper contains a brief explanation of the model used to recognize faces and predict the condition such as happy, sadness, fear, anger, disgust, natural, surprise. Local Directional Number Pattern (LDNP) technique is proposed to extract the features of the face and categorized with one of the algorithms for classification. LDNP encrypts directional information of the facial texture in a compact way to eight different directions through calculating the edge responses in the neighborhood, by choice most positive and negative directions of those edge responses to produce a descriptor. Positive and negative directions provide sufficient information on the structure of the neighborhood. It allows distinguishing the intensity changes for example from light to dark and dark to light. The LDNP is a method more compact than previous methods in which they can extract many facial features that integrate with each other into a feature vector, which is then, used it as a face descriptor. This approach is extended in this work to improve recognition accuracy. In the existing method, Support Vector Machine (SVM) with LDNP approach which used for facial expression. The performance of SVM is destitute. In the proposed model Feed Forward Neural Network (FFNN), is used to improve the accuracy performance.

Coding Facial Expressions with Gabor Wavelets
Conference Paper
Full-text available
  • May 1998
A method for extracting information about facial expressions from images is presented. Facial expression images are coded using a multi-orientation multi-resolution set of Gabor filters which are topographically ordered and aligned approximately with the face. The similarity space derived from this representation is compared with one derived from semantic ratings of the images by human observers. The results show that it is possible to construct a facial expression classifier with Gabor coding of the facial images as the input stage. The Gabor representation shows a significant degree of psychological plausibility, a design feature which may be important for human-computer interfaces
