30. The system of claim 24 , wherein the matching processor determines the at least one matching image based on a correspondence between the query signature and the associated database image signatures.
30. The system of claim 24 , wherein the matching processor determines the at least one matching image based on a correspondence between the query signature and the associated database image signatures. 31. The system of claim 30 , wherein the correspondence is determined using the equation: auto ⁢ ⁢ ( S I q , S I db ) := min j 1 ≤ j q < j 2 j 1 ≤ j db < j 2 0 ≤ w ≤ 1 ⁢ { w ⁢ ⁢ ρ ⁢ ( v j q q , v j db db ) + ( 1 - w ) ⁢ ρ ⁡ ( v j q + 1 q , v j db + 1 db ) } where S represents the signature, I q represents a query image, I db represents a database image, w represents a floating point number between zero (0) and one (1), ρ represents a distance, v represents a center of curvelet function φ j,l,k , and j represents a scale.
