Abstract

본 논문에서는 향상된 물체 인식을 위한 픽셀 복원 기반의 비선형 3D 상관기를 제안한다. 제안한 방법은 부분적으로 가려진 물체로부터 요소영상을 픽업하고 서브영상으로 변환하고 영역 매칭 알고리즘 방법을 이용하여 서브영상으로부터 장애물로 가려진 영역을 검출하고 제거한다. 그 다음 픽셀 복원 방법으로 각 서브영상에서 제거된 물체의 픽셀을 복원한다. 마지막으로, 재생된 참조영상과 재생된 영상 사이의 비선형 상호상관을 통하여 3D 물체의 인식 성능을 향상 시킨다. 제안된 방법의 유용함을 보이기 위해 기존 방법과 비교하여 기초적인 상관관계 실험을 수행하고 그 결과를 보고한다. In this paper, we propose a performance-enhanced object recognition by using nonlinear 3D correlator based on pixel restoration. In the proposed method, elemental images of the 3D target that are partially occluded by a foreground object are picked up and transformed into sub-images. By using the block-matching algorithm, the occluded target regions of each sub-image are estimated and removed. After that, the missing pixels in each sub-image are reestablished by using the pixel-restoration method. Finally, through the nonlinear cross-correlations between the reconstructed reference and the target plane images, the improved object recognition can be performed. To show the feasibility of the proposed method, some preliminary experiments are carried out and results are presented by comparing the conventional method.
