	Document Image Compression and Analysis
		The initial breakthroughs in the compression of one-dimensional signals [109] were easily extended to the image domain by concatenating image rows or columns into a single stream.
		As is well known, the performance of conventional compression algorithms (such as those based on transform coding [44], vector quantization [30], fractal compression [12], pattern matching and substitution [10, 64], and other approaches) depends on the types of images being compressed, and on their texture and content characteristics.
		This paves the way for compression by packing the energy in the error stream, for lossy compression by terminating the error stream at an index calculated by the signal-to-noise ratio, and for progressive transmission by interleaving the error signals for a set of image marks based on their distance order [49].

		In functional analysis, the spectrum of an operator is defined as the set of all its spectral values.
		In functional analysis, the concept of the spectrum of an operator is a generalisation of the concept of eigenvalues, which is much more useful in the case of operators on infinite-dimensional spaces.
		In factor analysis, the eigenvectors of a covariance matrix correspond to factors, and eigenvalues to factor loadings.

	Compression (functional analysis) - Wikipedia, the free encyclopedia
		In functional analysis, the compression of a linear operator T on a Hilbert space to a subspace K is the operator
		If K is an invariant subspace for T, then the compression of T to K is the restricted operator K→K sending k to Tk.

	AN APPROACH TO THE FUNCTIONAL ANALYSIS OF BILL SHAPE (Site not responding. Last check: 2007-10-09)
		The compression force that acts on the ventral surface of the upper jaw of the Cardinal is trans- mitted to the dorsal surface by the set of trabeculae lying anterior to the nasal cavity.
		Hofer argues from this analysis that the curvature of the culmen should be one that would reduce the angle between the force line P and the vector m to a minimum; hence the stress represented by the component n would be minimal.
		From this analysis, it can be seen that when the curvature of the culmen is large at the point of intersection with vector P (the angle between the vector and the tangent to the curvature approaching 0ø), the compression component m is large and the fracture-risk component n is small.

	Data compression (Site not responding. Last check: 2007-10-09)
		In computer science, data compression or source coding is the process of encoding information using fewer bits (or other information-bearing units) than a more obvious representation would use, thanks to specific encoding schemes.
		As is the case with any form of communication, compressed data communication only works when both the sender and receiver of the information understand the encoding scheme.
		Compression is important because it helps reduce the consumption of expensive resources, such as disk space or connection bandwidth.

	Shift operator - Wikipedia, the free encyclopedia
		In mathematics, and in particular functional analysis, the shift operators are examples of linear operators, important for their simplicity and natural occurrence.
		This operation respects typical convergence conditions, such as absolute convergence of the corresponding infinite series; it therefore gives rise to continuous operators on the standard sequence spaces used in functional analysis, usually with norm 1.
		The theory of analytic functions is related to that of polynomials, by allowing infinite power series; on the other hand meromorphic functions have Laurent series that terminate in the direction of negative exponents.

		The functional analysis has shown that combining traces by means of interleaving reduces the burstiness compared to individual traces before interleaving.

		He noted that the patient had not had a complete neurological examination in nearly three years, had never had such advanced testing as positron emission tomography (PET) or functional magnetic resonance imaging (fMRI), and that in the absence of such examination and imaging there remained "huge uncertainties" about her neurological status.
		Functional magnetic resonance imaging in particular has enabled neuroscientists to detect brain activity in patients previously diagnosed as being in persistent vegetative states.
		Neurologists can pinpoint the precise location of injured areas, know exactly what the functions of those areas are supposed to be, and still have no idea what actual deficits the patient will or will not experience: every brain, I was told by a neuroscientist at UCLA, is wired differently.

		The Bramble-Hilbert lemma is frequently applied to the analysis of Finite Element Methods (FEM) used for numerical solutions of PDEs.

		Abstract: The use of the wavelet transform is explored for the detection of differences between brain functional magnetic resonance images (fMRI's) acquired under two different experimental conditions.
		The method benefits from the fact that a smooth and spatially localized signal can be represented by a small set of localized wavelet coefficients, while the power of white noise is uniformly spread throughout the wavelet space.
