Patent ID: 8798136

Claim:
A method of generating an image representation, comprising: a. receiving or generating a digitized image, wherein said digitized image comprises a first plurality of pixels arranged in a first two-dimensional array, a width of said digitized image is along a first dimension of said first two-dimensional array, and a height of said digitized image is along a second dimension of said first two-dimensional array; b. forming from said first plurality of pixels of said digitized image a first group of a second plurality of pixels and a second group of a third plurality of pixels, wherein said first group of said second plurality of pixels provides for displaying a representation of said digitized image having a relatively lower resolution relative to a resolution of said digitized image of said first plurality of pixels in said first two-dimensional array, a count of said second plurality is smaller in value than a count of said first plurality, at least one pixel of said first group of said second plurality of pixels is formed from an algebraic combination of at least two pixels of said first plurality of pixels, and said first and second groups of said second and third pluralities of pixels together provide for reconstructing said first two-dimensional array of said digitized image therefrom substantially without loss of associated information, wherein either a selection or an algebraic combination of pixels from said first or second groups of said second or third pluralities of pixels is sufficient to provide for reconstructing said first two-dimensional array of said digitized image substantially without loss of associated information, and c. generating at least one image representation from at least one of said first group of said second plurality of pixels or said second group of said third plurality of pixels.
