Abstract. This presentation is intended for the general audience. No background in advanced mathematics is required to follow at least the first half of the talk. With the current rapid technological advancement in image data acquisition, the high demand for innovative methods to manipulate and understand large volumes of high-dimensional image data is more urgent than ever. We will be concerned with the manifold approach to image data representation and processing. Understanding of images in terms of spectral curves will be discussed in some detail. We will present an unsupervised data re-organization method, called anisotropic transform, and its integration with random projection for fast computation with arbitrary pre-assigned accuracy in the probability sense. Applications to be discussed include cancerous tissue detection, agricultural control, homeland security, and fast image search. This is a joint work with Jianzhong Wang |
