This paper presents a novel iris coding method based on differences of discrete cosine
transform (DCT) coefficients of overlapped angular patches from normalized iris images. The …

A simple mathematical model is developed which computes fingerprint local ridge
orientation from core and delta positions. This model provides an intelligent tool for resolving …

A generalization of fractal coding of images is presented in which image blocks are
represented by mappings derived from least squares approximations using fractal functions. …

A method for block coding of images based on a least squares fractal approximation by a
self-affine system (SAS) is presented. The computational cost of the approximation is linear in …

The resilience of identity verification systems to subsampling and compression of human iris
images is investigated for three high-performance iris-matching algorithms. For evaluation, …

A human iris coding technique is reported based upon differences in the power spectrum of
fragments from normalized iris images. The procedure has been applied to a set of 2174 …

… By and large the people I contacted as I sought a greater understanding of Monro were …
her own preliminary search for materials about Monro. Then Monro’s daughter and son-in-law, …

An original method is presented for the efficient fractal approximation of rectangular grey-scale
image blocks. Its application to the block coding of images is applied to standard test …

A novel eyelash removal method for preprocessing of human iris images in a human iris
recognition system is presented. The method filters each occluded pixel along an axis …

Image analysis was carried out on images of laboratory-made synthetic sandstone, which is
used in air injection/in situ combustion experiments, and statistically similar sandstone was …
