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...

This paper presents invariants under gamma correction and similarity transformations. The invariants are local features based on differentials which are implemented using derivatives of the Gaussian. The use of the proposed invariant representation is shown to yield improved correlation results in a template matching scenario.

Inter prediction is an important component for video coding which exploits the temporal correlation between frames and significantly reduces the redundancy in video sequences. In this paper, we propose a predictive patch matching for inter prediction based on template matching prediction. Besides the surrounding reconstructed pixels which form the template in template matching prediction, our p...

-Template matching is a fundamental technique of pattern recognition. Although this technique is very general, its applicability has been limited because of the difficulty often encountered when fitting templates to natural data. Natural patterns are often distorted, misshapen, stretched in size, fuzzy, rotated, translated, observed at an unusual perspective, etc. Flexible templates (rubber mas...

How does one extract unknown but stereotypical events that are linearly superimposed within a signal with variable latencies and variable amplitudes? One could think of using template matching or matching pursuit to find the arbitrarily shifted linear components. However, traditional matching approaches require that the templates be known a priori. To overcome this restriction we use instead se...
