Abstract
A method for generating a high-resolution image from a plurality of low-resolution images generated from quantized coefficients in the spatial frequency domain and the uncertainties in the quantized coefficients. The method generates a set of linear inequalities relating the quantized coefficients, the uncertainties therein, and the pixel values for the high-resolution image. Each linear inequality relates one of the quantized coefficients to a linear sum of the high-resolution pixel values. A high-resolution image whose pixels satisfy this set of inequalities is then generated
