An adaptive two step paradigm for the super-resolution of optical images is developed in this paper. The procedure locally projects image samples onto a family of kernels that are learned from image data. First, an unsupervised feature extraction is performed on local neighborhood information from a training image. These features are then used to cluster the neighborhoods into disjoint sets for...

We study the problem of linear approximation of a signal using the parametric Gamma bases in L2 space. These bases have a time scale parameter which has the effect of modifying the relative angle between the signal and the projection space, thereby yielding an extra degree of freedom in the approximation. Gamma bases have a simple analog implementation which is a cascade of identical lowpass fi...

A 1352-nucleotide intron within the Euglena gracilis chloroplast ycf8 gene has been characterized as a complex twintron with overlapping internal introns and alternative splicing pathways. Partially spliced pre-mRNAs were characterized by a combination of cDNA cloning and sequencing, Northern hybridization, and S1 nuclease protection analyses. In the predominant pathway, two internal group II i...
