⎯ This paper is to present vision based motion analysis for human-robot interaction, which analyzes camera motion and human motion. Motion of camera is compensated by comparing edge features among consecutive image frames. Candidate regions of human motion are found by differencing between transformed t image and t-1 image. Human motion is finally decided by image features and motion analysis. ...

This paper describes a machine learning approach for visual object detection which is capable of processing images extremely rapidly and achieving high detection rates. This work is distinguished by three key contributions. The first is the introduction of a new image representation called the “Integral Image” which allows the features used by our detector to be computed very quickly. The secon...

The authors propose a face recognition algorithm robust against the illumination variations, using an average face shape. The objective of this paper is two-fold: (1) to propose a new algorithm to estimate one of the illumination-invariant features, i.e., the surface reflectance from single appearance image, and (2) to apply this algorithm to images with various illumination conditions. In (11,...

As intelligent environments become more focused on supporting human activity, we see a growing need for the computer to ascertain users’ location and activity, be it for face detection, gesture recognition, or even simple tracking. To support such applications, a robust tracking algorithm is required. A camera tracking algorithm for a pan and tilt camera is proposed, that is robust to moderatel...

-The purpose of this study was focused on the learning behavior and performance of asynchronous distance learning with face recognition system among in-service teachers. There were 48 participants invited. In this study, teacher's gender, age, job status, educational level, school level, and school district were analyzed to explore the differences in learning behaviors and performance. The resu...

background: considering differences in head size and shape of different equine breeds, biometric parameters can be an attribute to a particular race. objectives: the purpose of the present paper is to give a numerical definition of morphological characteristics of head region of the darehshori horse. methods: twenty mature darehshori horses were studied biometrically. the ear length, ears dista...

It has been proposed that faces are represented in the visual brain as points within a multi-dimensional "face space", with the average at its origin. We adapted a psychophysical procedure that measures non-linearities in contrast transduction (by measuring discrimination around different reference/pedestal levels of contrast) to examine the encoding of facial-identity within such a notional sp...

Face identity aftereffects suggest that an average face, which is continuously updated by experience, functions as a norm for coding identity. Sex-contingent figural face aftereffects indicate that different norms are maintained for male and female faces but do not directly implicate them in coding identity. Here, we investigated whether sex-specific norms are used to code the identities of mal...
