讲座摘要：Due to the rapid development of imaging technologies, we have obtained a large amount of biomedical images. In addition to 3-dimensional spatial information, the biomedical images have temporal information. Efficient representation of the multi-dimensional biomedical image is an important issue for biomedical image analysis. Sparse coding is one of machine learning methods and is widely used for efficient image representation and image recognition. The limitation of the conventional sparse coding is that a multi-dimensional data (e.g. an image or a video image) should be unfolded into a vector resulting in loss of spatial and spatial-temporal relationship of the data. In this keynote talk, I will talk about anew tensor sparse coding method and its application to multi-dimensional medical image analysis, in which the multi-dimensional data can be treated as a tensor without unfolding.
