Tree topology estimation

Journal article IEEE Transactions on Pattern Analysis and Machine Intelligence · August 1, 2015 Featured Publication Tree-like structures are fundamental in nature, and it is often useful to reconstruct the topology of a tree-what connects to what-from a two-dimensional image of it. However, the projected branches often cross in the image: the tree projects to a planar g ... Full text Cite

Compressed wavefront sensing.

Journal article Opt Lett · March 1, 2014 Featured Publication We report on an algorithm for fast wavefront sensing that incorporates sparse representation for the first time in practice. The partial derivatives of optical wavefronts were sampled sparsely with a Shack-Hartman wavefront sensor (SHWFS) by randomly subsa ... Full text Link to item Cite

Fast acquisition and reconstruction of optical coherence tomography images via sparse representation.

Journal article IEEE Trans Med Imaging · November 2013 Featured Publication In this paper, we present a novel technique, based on compressive sensing principles, for reconstruction and enhancement of multi-dimensional image data. Our method is a major improvement and generalization of the multi-scale sparsity based tomographic den ... Full text Link to item Cite

Efﬁcient fourier-wavelet super-resolution.

Journal article IEEE Trans Image Process · October 2010 Featured Publication Super-resolution (SR) is the process of combining multiple aliased low-quality images to produce a high-resolution high-quality image. Aside from registration and fusion of low-resolution images, a key process in SR is the restoration and denoising of the ... Full text Link to item Cite

Fast and robust multiframe super resolution.

Journal article IEEE transactions on image processing : a publication of the IEEE Signal Processing Society · October 2004 Featured Publication Super-resolution reconstruction produces one or a set of high-resolution images from a set of low-resolution images. In the last two decades, a variety of super-resolution methods have been proposed. These methods are usually very sensitive to their assume ... Full text Cite
