The tension control of wires can benefit from Series Elastic Actuator (SEA), which is a potential emerging actuator system. In this paper, it is verified that the tension of wires can be successfully controlled by a novel SEA, called Compact Planetary-geared Elastic Actuator (cPEA), which incorporates a planetary gear and a spring to achieve precise force sensing and compactness at the same time....
In this paper we present a novel way of applying Zernike moments for image matching. Zernike moments are obtained from projecting image information under a circumscribed circle to Zernike basis function. However, the problem is that the power of discrimination may be reduced because hand images include lots of overlapped information due to their shape characteristic. On the other hand, in the pose...
In this paper we present a face orientation angle recognition system based on a modified Hausdorff distance. The Hausdorff distance determines the similarity between a given test image and a template. However, this operation is slow due to that the whole image is considered while using the original Hausdorff distance for matching. To address this matter we propose a divided Hausdorff distance which...
This paper presents a face orientation angle recognition system based on hausdorff distance matching from 2D image. The hausdorff distance can determine the degree of resemblance between an image and a model. The proposed system measures the angle of face orientation using Modified six hausdorff distance matching method after finding canny edge of the image and interpolation.
In this paper, a real time dynamic gesture recognition method based on a modified Levenshtein distance is proposed. The method addresses the issues faced in dynamic gesture recognition methods that are due to gesture variability within the class due to differences in the gesture speed. Since the gesture speed and duration will vary from one gesture to another, or from one person to the next, without...
In this paper, we propose a mapping and navigation method for mobile robots with low computational resources and limited memory capacity. The proposed navigation method is based on topological mapping of visual features for its compact representation and robustness in localization. In order to improve the localization accuracy and minimize the memory requirement, we propose the use of visual features...
We studied the active layer thickness dependence of device performance of bulk heterojunction solar cells. The polymer solar cells comprising RR-P3HT:PCBM (1:0.8 (wt %:wt%)) blend films with different thickness (from 80 nm to 340 nm) were characterized. The dissociation efficiency of photo generated e-h pairs determined from photo current-effective voltage characteristics. The dissociation efficiency...
