摘要:

在本文中,我们提出了一种新的基于学习的方法自动分割脑肿瘤的多模态MRI图像,它结合了两套机器学习和手工制作的功能。全卷积网络(FCN)形成机器学习的特征,基于纹理基元的特征被认为是手工制作的特征。随机森林(RF)用于将MRI图像体素分类为正常脑组织和肿瘤的不同部分,即水肿、坏死和增强肿瘤。在BRATS 2017挑战数据集上评价了该方法。结果表明,该方法提供了有前途的分割。对于整个肿瘤、核心和增强肿瘤,针对地面实况的自动脑肿瘤分割的平均Dice重叠度量分别为0.86、0.78和0.66。

英文摘要:

In this paper, we propose a novel learning based method for automated segmentation of brain tumor in multimodal MRI images, which incorporates two sets of machine -learned and hand crafted features. Fully convolutional networks (FCN) forms the machine learned features and texton based features are considered as hand-crafted features. Random forest (RF) is used to classify the MRI image voxels into normal brain tissues and different parts of tumors, i.e. edema, necrosis and enhancing tumor. The method was evaluated on BRATS 2017 challenge dataset. The results show that the proposed method provides promising segmentations. The mean Dice overlap measure for automatic brain tumor segmentation against ground truth is 0.86, 0.78 and 0.66 for whole tumor, core and enhancing tumor, respectively.
