Facial expression recognition using human machine interaction and multi-modal visualization analysis for healthcare applications

摘要

The application of computer vision (CV) in healthcare applications is familiarwith the wireless and communication technology. CVmethods are incorporated in the healthcare for providing programmed interactions towards patientmonitoring. The requirements of systems are the analysis and detection of the images' visualization of patients. In this paper, a multi-modal visualization analysis (MMVA) method is introduced for improving the lesscomplex processing nature of programmed human-machine interactions (HMI) in health monitoring. In particular, the proposed method is designed to identify facial expressions of a patient using facial expression and textures of the input visualization. The proposedmethod relies on three layers of convolution neural network (CNN) for texture classification, correlation, and detection of facial visualization using stored information. The processes of the three-layers are chained to reduce the complexity and misdetection in the analysis. The feature-based tuning chain in the first layer of CNN attains to minimize the impact of facial and textural variants resulting in misdetection. The second layer is a correlation to attain the accurate matching of expression from the captured image. The third layer is facial visualization to find the quick decision and used to store the error data as the training set. The experimental results show that proposed method achieves 95.702% of recognition accuracy compared to other conventional methods. The analysis time and misdetection are minimized. Also, the recognition ratio is improved. (c) 2020 Elsevier B.V. All rights reserved.
