Recovery of an image from a finite set of irregularly spaced samples is considered. A method of ranking the quality of such sampling sets described by Chen and Alleback is extended to the case of unequal numbers of samples. Calculations provide information on the relative effects of sample number, density and nonuniformity on reconstruction error.
