“…Some applications include human/object detection and recognition based on vision object analysis and processing areas such as tracking and detection [1,2], computer engineering [3], physical sciences [4], health-related issues, natural sciences, and industrial academic areas [5]. Most of the authors [6][7][8][9][10][11] recognized the human activities in indoor environments based on different methodologies. However, in their respective systems, they used stable environment like fixed camera setting and prelighting setting, and most of the activities were performed by the instructions provided by the instructor.…”

In healthcare, the analysis of patients’ activities is one of the important factors that offer adequate information to provide better services for managing their illnesses well. Most of the human activity recognition (HAR) systems are completely reliant on recognition module/stage. The inspiration behind the recognition stage is the lack of enhancement in the learning method. In this study, we have proposed the usage of the hidden conditional random fields (HCRFs) for the human activity recognition problem. Moreover, we contend that the existing HCRF model is inadequate by independence assumptions, which may reduce classification accuracy. Therefore, we utilized a new algorithm to relax the assumption, allowing our model to use full-covariance distribution. Also, in this work, we proved that computation wise our method has very much lower complexity against the existing methods. For the experiments, we used four publicly available standard datasets to show the performance. We utilized a 10-fold cross-validation scheme to train, assess, and compare the proposed model with the conditional learning method, hidden Markov model (HMM), and existing HCRF model which can only use diagonal-covariance Gaussian distributions. From the experiments, it is obvious that the proposed model showed a substantial improvement with p value ≤0.2 regarding the classification accuracy.
