5. The method of claim 3 , wherein said plurality of scores for said next higher resolution version of said image comprise appearance scores, geometric scores and resolution context scores.
5. The method of claim 3 , wherein said plurality of scores for said next higher resolution version of said image comprise appearance scores, geometric scores and resolution context scores. 6. The method of claim 5 , wherein said weighted average score for the next higher resolution version of the image is computed using the following formula divided by I: ∑ i ⁢ W 1 ⁡ ( A i ) + W 2 ⁡ ( G i ) + W 3 ⁡ ( R i ) wherein I represents the number of regions in the next higher resolution version of the image, i is a region index, ∑ i denotes a summation from i=1 to i=I, A i represents appearance scores in region i, G i represents geometric scores in region i, R i represents resolution context scores in region i, and W 1 , W 2 and W 3 represent weights respectively assigned to the appearance scores, the geometric scores, and the resolution context scores.
