Abstract
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

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
85 words
In a method for generating a high-resolution image comprising a plurality of high-resolution pixel values from a plurality of low-resolution images, each low-resolution image being generated from coefficients in a spatial frequency domain, each of said coefficients in said spatial frequency domain having a known uncertainty associated therewith, the improvement comprising the steps of: generating a plurality of linear inequalities relating said coefficients, the uncertainties therein, and pixel values for said high-resolution image; and determining a set of high-resolution pixel values satisfying said linear inequalities.
Claim 2
Dependent Claim
85 words
In a method for generating a high-resolution image comprising a plurality of high-resolution pixel values from a plurality of low-resolution images, each low-resolution image being generated from coefficients in a spatial frequency domain, each of said coefficients in said spatial frequency domain having a known uncertainty associated therewith, the improvement comprising the steps of: generating a plurality of linear inequalities relating said coefficients, the uncertainties therein, and pixel values for said high-resolution image; and determining a set of high-resolution pixel values satisfying said linear inequalities.
Claim 3
Dependent Claim
34 words
The method of claim 1 wherein said step of determining said set of high-resolution pixels comprises making an initial estimate of said high-resolution image by interpolating pixel values of one of said low-resolution images.
Claim 4
Dependent Claim
76 words
The method of claim 1 wherein said step of generating said set of linear inequalities comprises: estimating the location of a pixel in one of said low-resolution images corresponding to said pixel in another of said low-resolution images assuming a plurality of pixels around said pixel move between said low-resolutions images according to a predetermined relationship; and determining the extent to which each of said pixels in said plurality of pixels around said pixel actually moved.
