The mechanism of hallux valgus (HV) development has not been fully clarified, and a new evaluation method is required. We aimed to establish for calculating the rotational moment midfoot (RMM) by developing three-dimensional foot scanner, reveal features HV using this method. A smartphone was used capture images analyze regions in 592 participants. focused on feature points such as great toe-fi...

In this paper, a method is proposed for building occupancy grid based maps from sequences of stereo images in real time. The stereo camera can move and rotate unconstrained in three dimensions. This distinguishes the method from all other mapping approaches, which constrain the sensor to move in two dimensions. This freedom of motion allows to perform mapping in many new application areas. Addi...

This paper presents a sound-source-direction estimation method using only a single microphone with a parabolic reflection board. A simple signal-power-based method using a parabolic antenna has been proposed in the radar field. But the signal-power-based method is not effective for finding the direction of a talking person due to the varying power of the uttered speech signals. In this paper, t...

Entity type prediction is an important problem in knowledge graph (KG) research. A new KG entity method, named CORE (COmplex space Regression and Embedding), proposed this work. The method leverages the expressive power of two complex embedding models; namely, RotatE ComplEx models. It embeds entities types different spaces using either or ComplEx. Then, we derive a regression model to link the...
