Abstract

Claims (49)

1. A computer-implemented method, comprising:

receiving an image search criteria including at least one reference image and at least one contextual data;

generating a composite image search query including a synthetic image sketch based on a plurality of transformed segments from the at least one reference image, wherein the plurality of transformed segments include modifications based on the at least one contextual data;

searching for a matching historical image based on the generated composite image search query; and

returning a historical image search result.

2. The method of claim 1 , further comprising:

classifying at least one object detected in the at least one reference image;

modifying the classified at least one object detected in the at least one reference image based on the at least one contextual data; and

generating the synthetic image sketch including the modified at least one object detected in the at least one reference image.

3. The method of claim 1 , further comprising:

assigning an object classifier to an object detected in the at least one reference image;

determining a family of the object associated with the assigned object classifier;

selecting an aging algorithm based on the determined family of the object detected in the at least one reference image; and

transforming the object based on the selected aging algorithm.

4. The method of claim 1 , wherein the synthetic image sketch further comprises an aged back version of the at least one reference image, and wherein the aged back version of the at least one reference image includes modifying at least one object detected in the at least one reference image based on age.

5. The method of claim 1 , wherein the generated composite image search query further comprises at least one metadata added to the synthetic image sketch to describe the at least one contextual data associated with the matching historical image.

6. A computer system for historical image search, comprising:

one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage media, and program instructions stored on at least one of the one or more computer-readable tangible storage media for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:

receiving an image search criteria including at least one reference image and at least one contextual data;

generating a composite image search query including a synthetic image sketch based on a plurality of transformed segments from the at least one reference image, wherein the plurality of transformed segments include modifications based on the at least one contextual data;

searching for a matching historical image based on the generated composite image search query; and

returning a historical image search result.

7. The computer system of claim 6 , further comprising:

classifying at least one object detected in the at least one reference image;

modifying the classified at least one object detected in the at least one reference image based on the at least one contextual data; and

generating the synthetic image sketch including the modified at least one object detected in the at least one reference image.

8. The computer system of claim 6 , further comprising:

assigning an object classifier to an object detected in the at least one reference image;

determining a family of the object associated with the assigned object classifier;

selecting an aging algorithm based on the determined family of the object detected in the at least one reference image; and

transforming the object based on the selected aging algorithm.

9. The computer system of claim 6 , wherein the synthetic image sketch further comprises an aged back version of the at least one reference image, and wherein the aged back version of the at least one reference image includes modifying at least one object detected in the at least one reference image based on age.

10. The computer system of claim 6 , wherein the generated composite image search query further comprises at least one metadata added to the synthetic image sketch to describe the at least one contextual data associated with the matching historical image.

11. A computer program product for historical image search, comprising:

one or more computer-readable storage media and program instructions collectively stored on the one or more computer-readable storage media, the program instructions executable by a processor to cause the processor to perform a method comprising:

receiving an image search criteria including at least one reference image and at least one contextual data;

generating a composite image search query including a synthetic image sketch based on a plurality of transformed segments from the at least one reference image, wherein the plurality of transformed segments include modifications based on the at least one contextual data;

searching for a matching historical image based on the generated composite image search query; and

returning a historical image search result.

12. The computer program product of claim 11 , further comprising:

classifying at least one object detected in the at least one reference image;

modifying the classified at least one object detected in the at least one reference image based on the at least one contextual data; and

generating the synthetic image sketch including the modified at least one object detected in the at least one reference image.

13. The computer program product of claim 11 , further comprising:

assigning an object classifier to an object detected in the at least one reference image;

determining a family of the object associated with the assigned object classifier;

selecting an aging algorithm based on the determined family of the object detected in the at least one reference image; and

transforming the object based on the selected aging algorithm.

14. The computer program product of claim 11 , wherein the synthetic image sketch further comprises an aged back version of the at least one reference image, and wherein the aged back version of the at least one reference image includes modifying at least one object detected in the at least one reference image based on age.
