Impedance may be defined as a measure of the amplitude and phase of opposition to the flow of a current. Impedance is a fundamental concept, of universal validity. Impedances govern energy flow. Classical or quantum impedances, geometric or topological, scale invariant or scale dependent, fermionic or bosonic, mechanical or electromagnetic or gravitational impedance matching governs the flow of...

In this paper, a novel template matching algorithm named radial ring code histograms(RRCH) for multi-objects positioning is proposed. It is invariant to translation, rotation and illumination changes. To improve the identification ability of multi objects with different rotation angles, radial gradient codes using relative angle between gradient direction and position vector is proposed. Adjust...

This paper describes a method to extract facial features from front and side views for 3D facial model creation by modifying a 3D generic head model. Front and side views of a person's face are taken simultaneously by two cameras under the same geometric condition. The side view (profile) is first analyzed using a DP template matching to extract vertical locations of nose and mouth. Then, by us...

Patients with aphasia often have impaired speech-language production skills, resulting in tremendous difficulties in tasks that require verbal communication. To facilitate rehabilitation outside of therapy, we are collaborating with the University of Michigan Aphasia Program (UMAP) to develop an automated system capable of providing feedback regarding the patient’s verbal output. In this paper ...

the three-dimensional search area In this paper, we propose an efficient technique for tracking three-dimensional palm motion, which is captured by two cameras. If we perform template matching independently for each image, two points in two images do not always correspond to each other. Thus we propose to set the search area in the three-dimensional space, not in image planes, so that we can fi...

We propose a novel object detection and tracking method in order to detect and track objects necessary to describe contents of a soccer game. On the contrary to intensity oriented conventional object detection methods, the proposed method refers to color rarity and local edge property, and integrally evaluate them by a fuzzy function to achieve better detection quality. These image features wer...
