Analysis of threshold modulations in one-dimensional error diffusion
Daels, K.; Easton, Roger; Eschbach, R. (Elsevier Science B.V., Amsterdam, 1992-01-15)Error diffusion is a numerical method for the binarization of continuous tone data. Modified error diffusion algorithms exist that introduce threshold modulations into the process. this article generalizes an analytical ... -
Automatic image annotation using adaptive color classification
Saber, Eli; Tekalp, M.; Eschbach, R.; Knox, K. (Elsevier Academic press, 1996-03)We describe a system which automatically annotates images with a set of prespecified keywords, based on supervised color classification of pixels into N prespecified classes using simple pixelwise operations. The conditional ... -
Error diffusion in cell-oriented Fourier-transform computer-generated holograms to compensate for printing constraints
Easton, Roger; Eschbach, R.; Nagrajan, R. (Taylor & Francis, 1996-06-01)Error-diffused quantization has been applied to the generation of cell-oriented computer-generated Fourier transform holograms, resulting in reduced reconstruction errors. Improvements are demonstrated when applied to the ...
