초록

본 논문은 특징 정보 예측을 통한 빠른 보행자 검출 기법을 제안한다. 다양한 크기의 보행자를 검출하기 위해 보행자 모델의 크기나 입력영상의 크기를 변화시킨다. 보행자 모델의 크기를 변화시킬 경우 크기별 모델이 필요하며, 보행자 모델의 크기의 축소시키는 경우 모델 정보를 손상시킨다. 보행자 모델의 다양한 크기별 보행자의 특징을 추출해야 하므로 보행자 특징의 추출은 전체 수행시간 중 가장 많은 시간을 필요로 한다. 따라서 본 논문은 영상 크기에 따라 특징 추출을 반복하지 않고 입력영상에서 얻어진 특징 정보의 예측을 통해 보행자 검출의 특징추출을 수행한다. 제안하는 방법의 효율성을 검증하기 위해 다양한 채널을 가진 ChnFtrs 특징 및 Adaboost 알고리즘을 사용과 학습과 실험을 위한 영상으로 INRIA 보행자 DB를 사용하였다.

This paper enhances the speed of a pedestrian detection using an estimation of feature information based on integral image. Pedestrian model or input image should be resized to the size of various pedestrians. In case that the size of pedestrian model would be changed, pedestrian models with respect to the size of pedestrians should be required. Reducing the size of pedestrian model, however, deteriorates the quality of the model information. Since various features according to the size of pedestrian models should be extracted, repetitive feature extractions spend the most time in overall process of pedestrian detection. In order to enhance the processing time of feature extraction, this paper proposes the fast extraction of pedestrian features based on the estimate of integral image. The efficiency of the proposed method is evaluated by comparative experiments with the Channel Feature and Adaboost training using INRIA person dataset.
