It is estimated that one in three seniors fall at least once a year. Falls are a global problem for the elderly that affects their quality of life and poses a great risk. In our research, we are trying to develop a system that could prevent falls by estimating the fall risk in real time. The system would measure the balance of the user by measuring the position of the Center of Gravity inside the Base of Support. In our previous research, we presented a system with a millimeter wave radar attached to a cane to measure the area of the Base of Support. However, the obtained results for the foot position estimation error were significantly worse than similar studies. One of the reasons was that the sensor was not really estimating the position of the feet but the position of the lower legs. Therefore, in this research we present a correction model to improve the feet position estimation. The proposed model was able to reduce the foot position estimation RMSE from 54 mm down to 34 mm, which is closer to the results of other similar studies measuring the position of the feet.

© 2019 IEEE. In order to improve an application from the viewpoint of helping blind people waiting for the bus, classification of the vanishing view is required. The vanishing point from a perspective view is a feature that may improve the performance of viewpoint classification, especially in the case of congested traffic. The idea proposed by this study bases on the vanishing point estimation following car distribution on the road. In essence, the cars are detected using a You Only Look Once (YOLO) technique which extracts all the to the center point of a squared boundary. Normalization of the data points are then computed in percentages. Next is the calculation of the nineteen features of the data points of the car distribution. Finally, the vanishing point is estimated by supervised regression. This experiment compares the estimated results among five different regressions consisting of Linear, k-Nearest Neighbor, Decision Tree, Support Vector, and Multi-layer Per-ceptron regression. The obtain results show that the k-Nearest Neighbor regression computed the lowest distance error of 10.53, compared to the other regression algorithms.
