Content-based image retrieval (CBIR) has been one of the most active areas of research. The retrieval principle of CBIR systems is based on visual features such as colour, texture and shape or the semantic meaning of the images. A CBIR system can be used to locate medical images in large databases. This paper presents a CBIR system for retrieving digital human brain magnetic resonance images (MRI) based on textural features and the support vector machine (SVM) learning method. This system can retrieve similar images from the database in two groups: normal and tumoural. This research uses the knowledge of the CBIR approach to the application of medical decision support and discrimination between the normal and abnormal medical images based on features. This study presents and compares the results of the proposed method with the CBIR systems used in recent works. The experimental results indicate that the proposed method is reliable and has high image retrieval efficiency compared with the previous works.
基于内容的图像检索(CBIR)一直是最活跃的研究领域之一。CBIR系统的检索原理基于视觉特征,如颜色、纹理和形状,或图像的语义含义。CBIR系统可用于在大型数据库中定位医学图像。本文提出了一种基于纹理特征和支持向量机(SVM)学习方法的用于检索数字人脑磁共振图像(MRI)的CBIR系统。该系统可以从数据库中检索出两组相似图像:正常图像和肿瘤图像。本研究将CBIR方法的知识应用于医学决策支持,并基于特征对正常和异常医学图像进行区分。本研究展示并比较了所提方法与近期研究中使用的CBIR系统的结果。实验结果表明,与之前的研究相比,所提方法可靠且具有较高的图像检索效率。
