Abstract

This paper describes the algorithm that lowers the dimension, maintains the object recognition and significantly reduces the eigenspace configuration time by combining the higher correlation feature information and Principle Component Analysis. Since the suggested method doesn't require a lot of computation than the method using existing geometric information or stereo image, the fact that it is very suitable for building the real-time system has been proved through the experiment. In addition, since the existing point to point method which is a simple distance calculation has many errors, in this paper to improve recognition rate the recognition error could be reduced by using several successive input images as a unit of recognition with K-Nearest Neighbor which is the improved Class to Class method.

본 논문에서는 고차 상관 특정 정보와 주성분 분석을 결합하여 차원을 낮추면서도 객체 인식을 유지하고, 고유 공간 구성 시간을 현저하게 줄이는 알고리즘에 대해 기술한다. 제안된 방법은 기존의 기하학적 정보를 이용하거나 스테레오 영상을 이용하는 방법에 비해 많은 계산량이 요구되지 않기 때문에 실시간 시스템 구축에 매우 적합하다는 것이 실험을 통하여 증명되었다. 또한 인식률을 향상시키기 위해 단순히 기존의 방법인 point to point 방식인 단순 거리 계산은 오차가 많기 때문에 본 논문에서는 개선된 Class to Class방식인 K-Nearest Neighbor을 이용하여 몇 개의 연속적인 입력영상을 인식의 단위로 이용하여 인식 오차를 줄일 수 있었다.
