Human activity recognition by using convolutional neural network

Abstract: <p>In recent years, many researchers have studied the HAR (Human Activity Recognition) system. HAR using smart home sensor is based on computing in smart environment, and intelligent surveillance system conducts intensive research on peripheral support life. The previous system studied in some of the activities is a fixed motion and the methodology is less accurate. In this paper, vision-based studies using thermal imaging cameras improve the accuracy of motion recognition in intelligent surveillance sys… Show more

“…Since activity recognition learns and classifies images or patterns, it is important to consider the method of collecting images or data. Sometimes the data were collected with a depth camera consisting of RGB-D sensors [18]; another study employed a thermal camera capable of recognizing actions regardless of day or night [35]; in a study that implemented gesture recognition for smart home automation [41], they used Channel State Information (CSI) time-series data generated by performing gestures in front of a Wi-Fi router instead of a camera. The techniques for activity recognition are mainly based on supervised learning that matches and classifies data and designates labels of activities.…”

“…Problems between smart farms and data include: It is difficult to obtain enough data to be used for learning, and even the provided data has an adverse effect on learning due to unbalanced data per class [20][21][22][23]. Based on these problems, this paper proposes a method of amplifying the amount of data through a generative antagonistic neural network and generating data of various classes to solve the data imbalance between classes.…”
