Advances in CT image segmentation technology for plant roots in situ

The precise segmentation of roots CT images is the basis to implement the 3D reconstruction and quantitative analysis of plant root system in situ.The main methods of image segmentation used in the relevant fields are summarized.The characteristics and ap-plicability of these methods are discussed.The problem existing in the research on the CT image segmentation for plant roots in situ are analyzed.Some new ideas are put forwards for the further research.The characteristic of CT slice images and the transcendental know-ledge of roots' geometrical architecture should be considered fully in the new algorithms of root CT image segmentation.And the new relevant theory and methods including mathematical morphology approaches,fuzzy mathematics and neural network-based approaches should be used synthetically in the new algorithms.Its emphases are to improve the precision and robustness of algorithms.
