Retrieval of Brain Tumors with Region-Specific Bag-of-Visual-Words Representations in Contrast-Enhanced MRI Images
Figure 4
Dividing a tumor image in different modes. To ensure impartiality in the comparison between these two modes, we implement the partition in the tumor region instead of in the whole image as in [29]. (a) The partition mode used in [29]. There are 21 regions in this mode. (b) The partition mode used in our paper. There are six regions: the tumor region, the tumor-surrounding region, and the four subregions.
