Abstract

In this paper, we presents a pattern recognition by considering the spatial co-occurrence among micro-patterns of texture images. The micro-patterns of texture image have been extracted by local binary pattern based on median(MLBP) of block image, and the recognition process is based on co-occurrence among MLBPs. The MLBP is applied not only to consider the local character but also analyze the pattern in order to be robust noise, and spatial co-occurrence is also applied to improve the recognition performance by considering the global space of image. The proposed method has been applied to recognized 17 RGB images of 120*120 pixels from Mayang texture image based on Euclidean distance. The experimental results show that the proposed method has a texture recognition performance.

본 논문에서는 질감영상의 마이크로패턴 간 공간적인 동시발생 빈도를 고려한 패턴인식을 제안한다. 여기서 마이크로패턴은 블록영상의 중간값에 기반한 국소이진패턴(local binary pattern : LBP)으로 추출되고, 추출된 국소이진패턴들 사이의 동시발생빈도를 고려하여 패턴인식을 수행한다. 중간값 이진패턴은 영상의 국소속성을 고려할 뿐만 아니라 잡음에 강건한 패턴분석을 위함이고, 동시발생빈도는 영상의 전역속성을 고려하여 인식성능을 좀 더 향상시키기 위함이다. 제안된 기법을 120*120 픽셀의 17개 RGB 질감 패턴영상을 대상으로 유클리디언(Euclidean) 거리에 기반한 실험결과, 우수한 인식성능이 있음을 확인하였다.
