| Abstract(in English) | A conventional ensemble learning based segmentation often outputs unnatural shape, because of voxel-wise discrimination independent to its neighboring voxels. This study proposes an ensemble learning algorithm that minimizes not only error-related loss but also global shape-related loss. Actually the shape-related loss is defined as a summation of squared difference over an image between an extracted result in each learning stage and its reconstructed image from a shape sub-space. It is expected that an extracted shape becomes natural by minimizing a loss function with the shape-related loss. This paper shows effectiveness of the proposed algorithm by using a synthetic image. In addition, it presents results of applying this method to actual three dimensional CT images followed by discussion about the superiority against a conventional loss function without any shape-related loss. |
