Abstract : When an orthogonal projection is to be computed using data acquired by distributed sensors, it is often necessary to process each sensor's data locally and then transmit the results to a central facility for final processing. The most efficient way to do this is to compute oblique projections locally. This choice makes the final processing a matter of summing the oblique projections. This paper derives new formulas, and iterative algorithms and associated error bounds, for oblique projections in arbitrary Hilbert spaces.
