Abstract

Human pose estimation (HPE) is a procedure for determining the structure of the body pose and it is considered a challenging issue in the computer vision (CV) communities. HPE finds its applications in several fields namely activity recognition and human-computer interface. Despite the benefits of HPE, it is still a challenging process due to the variations in visual appearances, lighting, occlusions, dimensionality, etc. To resolve these issues, this paper presents a squirrel search optimization with a deep convolutional neural network for HPE (SSDCNN-HPE) technique. The major intention of the SSDCNN-HPE technique is to identify the human pose accurately and efficiently. Primarily, the video frame conversion process is performed and pre-processing takes place via bilateral filtering-based noise removal process. Then, the EfficientNet model is applied to identify the body points of a person with no problem constraints. Besides, the hyperparameter tuning of the EfficientNet model takes place by the use of the squirrel search algorithm (SSA). In the final stage, the multiclass support vector machine (M-SVM) technique was utilized for the identification and classification of human poses. The design of bilateral filtering followed by SSA based EfficientNet model for HPE depicts the novelty of the work. To demonstrate the enhanced outcomes of the SSDCNN-HPE approach, a series of simulations are executed. The experimental results reported the betterment of the SSDCNN-HPE system over the recent existing techniques in terms of different measures.
