Automatic liver tumor segmentation from CT images using hierarchical iterative superpixels and local statistical features

作者:

Highlights:

• A local information based SLIC is introduced for superpixel decomposition.

• A hierarchical iterative strategy is designed to produce homogeneous sub-regions.

• Various types of features are employed to discriminate between tumor and non-tumor.

• A Euclidean distance-based voting model is proposed to identify tumor region.

• Extensive experiments demonstrate the superiority of our method.
