Dense learning by high-dimensional self-organizing maps for interactive image segmentation
Takizawa,Hotaka
Proceedings of The 6th IIAE International Conference on Intelligent Systems and Image Processing 2018   332-336   Sep 2018   [Refereed]
This paper proposes an interactive image segmentation method based on self-organizing maps (SOMs). In this paper, not only two dimensional SOMs but also higher dimensional SOMs are used for image segmentation. The proposed method was applied to ac...
