Empirical formula for creating error bars for the method of paired comparison
(International Society for Optical Engineering (SPIE), 2006-01)
The method of paired comparison based on Thurstone’s
case V of his law of comparative judgments is often used as a psychophysical
method to derive interval scales of perceptual qualities
in imaging applications. However, ...
Image lightness rescaling using sigmoidal contrast enhancement functions
(International Society for Optical Engineering (SPIE), 1999-10)
In color gamut mapping of pictorial images, the lightness rendition of the mapped images plays a major role in the quality of the final image. For color gamut mapping tasks, where the goal is to produce a match to the ...
Application of spectral mixture analysis and image fusion techniques for image sharpening
(Elsevier Science B.V., Amsterdam, 1998-02)
Image fusion is used to merge images of different Spatial and spectral resolutions to create a high spatial resolution multispectral conibination. High spectral resolution allows identification of materials in the scene, ...
Image deconvolution using a micro genetic algorithm
(Elsevier - Optics Communications, 1997-07-15)
Image deconvolution is addressed using a modified Genetic Algorithm for the error minimization. Numerical examples
are presented to demonstrate the algorithm’s robustness. Specifically, noise levels and various regions ...
Accurate color reproduction of CRT: displayed images as projected 35mm slides
(International Society for Optical Engineering (SPIE), 1996-01-01)
Accurate color reproduction of images presented on a computer-controlled CRT display as projected 35-mm transparencies is a complicated procedure requiring the characterization and
control of several imaging processes and ...
Linear pixel shuffling for image processing, an introduction
(International Society for Optical Engineering (SPIE), 1993-04)
We investigate a method of ordering pixels (the elements of a rectangular matrix) based on an arithmetic progression with wrap-around (modular arithmetic). For appropriate choices of the progression's parameters, based on ...
Two-stage spatial-filtering for diffraction pattern-analysis
(Optical Society of America, 1981-03)
The use of optical power spectrum analysis for feature detection and classification is often restricted by the superposition of the aperture spectrum. A spatial frequency filtering technique using a circular aperture and ...
