Abstract : The Topical Meeting on Signal Recovery and Synthesis with Incomplete Information and Partial Constraints was held in Lake Tahoe, Nevada on January 12-14, 1983. The meeting was open to all interested scientists and engineers and was interdisciplinary in scope. The program consisted of both invited fields and contributed papers. The two and one-half day meeting dealt with such diverse as image processing, crystallography, astronomy, geophysical signal processing, electron microscopy, optical information processing, and remote sensing having encountered the problem of image formation with missing information or unknown (or only partially known) measurement system parameters. Specific examples include phase retrieval from intensity measurements, tomographic reconstruction with missing projections, blind deconvolution, and multidimensional spectral extrapolation and interpolation. A related set of problems occurs in multidimensional signal processing when system constraints are only partially specified. Examples include computer holography and pupil synthesis for incoherent optical processing. A common mathematical structure is shared by all these application areas. The purpose of this meeting was to bring together specialists with interests in these diverse areas and to stimulate interchange of ideas. (Author)
