Various obstacles such as large containers and logistics machines are placed, in an environment such as a spacious port that is difficult to monitor at once. We studied object detection methods to track very small pedestrians and port vehicle objects. Since we need to learn small objects and unclear shapes, we trained a model based on CenterNet, a network of Anchor-Free methods, and to supplement information on very small objects, we learned by stacking several consecutive images. In addition, Lack of datasets due to the special environment was solved by enhancing data that uses multiple datasets together, randomly selecting multiple still images, and processing them into a continuous image, thereby preventing overfitting.
Estimation of Finger Motion using Transient EMG Signals
http://doi.org/10.5626/JOK.2022.49.2.157
In this paper, we propose a deep learning model for estimating finger movements based on EMG signals. We have also evaluated and analyzed the accuracy of the model. We have applied the U-Net structure, which is widely used in medical image analysis, to our model. In general, U-Net is mainly used for processing of two-dimensional images. However, in this paper, 8-channel one-dimensional time series EMG data is used as inputs, and information about finger movement is obtained as results. We have acquired the data set consisting of 8,000 motions, which is divided into the training and evaluation data sets. The accuracy of the prediction of our model is about 89.32%.
