Patent ID: 8331711

Claim:
Method of enhancing a first structure (S 1 ) of samples into a second structure (S 2 ) of samples, the first and the second structure both representing a first property of a scene and having a first resolution, based on a third structure (S 3 ) of samples representing a second property and having the first resolution, the first property and the second property respectively representing different properties of substantially the same scene, the method comprising: generating ( 620 ) a fourth structure (S 4 ) of samples representing the first property, the fourth structure (S 4 ) of samples having a second resolution lower than the first resolution, by down-scaling first samples of the first structure (S 1 ) of samples to form the samples of the fourth structure (S 4 ) of samples; up-scaling ( 630 ) the fourth structure (S 4 ) of samples representing the first property, into the second structure (S 2 ) of samples based on the third structure (S 3 ) of samples, the up-scaling ( 630 ) comprising: i) assigning weight factors ( 702 ) to respective samples of the fourth structure (S 4 ) of samples based on samples of the third structure (S 3 ) of samples; and ii) computing ( 704 ) samples of the second structure (S 2 ) of samples using the samples of the fourth structure (S 4 ) of samples and their respectively assigned weight factors.
