摘要: 针对肠道肿瘤图像样本有限导致肿瘤识别率低和收敛速度慢的问题, 提出一种基于局部二值模式(LBP)和灰度共生矩阵(GLCM)的肠道肿瘤图像特征提取方法. 首先, 利用最大类间方差法自动计算图像灰度阈值, 进行感兴趣区域的提取; 然后, 采用LBP+GLCM对肠道肿瘤部分图像进行特征提取, 并利用支持向量机识别. 对1 500张肠道肿瘤图像进行实验的结果表明, 该方法可达到94.84%的识别准确率, 能有效辅助医学诊疗.

Abstract: Aiming at the problems of low tumor recognition rate and slow convergence speed caused by limited samples of intestinal tumor images, we proposed a feature extraction method of intestinal tumor images based on local binary pattern (LBP) and gray level co-occurrence matrix (GLCM). Firstly, the maximum interclass variance method was used to automatically calculate the image gray threshold and extract the region of interest. Secondly, the LBP+GLCM was used to extract the features of partial intestinal tumor image, and support vector machine was used for recognition. Experimental results of  1 500 intestinal tumor images show that this method can achieve 94.84% recognition accuracy and can effectively assist medical diagnosis and treatment.

Key words: intestinal tumor, region of interest, local binary patterns (LBP), grey level co-occurrence matrix (GLCM), support vector machines (SVM)
