Abstract

A method for synthesizing images includes selecting a background image from a plurality of source images and selecting one or more foreground elements from a plurality of source files. The foreground elements include at least one of a foreground image or a foreground text. The method further includes dividing at least a portion of the selected background image to one or more sub-regions for displaying the one or more selected foreground elements, each sub-region is used for displaying at least one foreground element. The method further includes determining a display format and a display location for each of the one or more foreground elements and synthesizing the one or more foreground elements to the corresponding one or more sub-regions of the background image based on the display format and the display location.

First claim

What is claimed is:

1. A computer-implemented method for providing multiple distinct, synthesized images that each include a same background image and a same foreground element, the method comprising:
selecting a background image and quantity n foreground elements that are both to be used to generate each of multiple, distinct synthesized images;
selecting a sub-region of the background image in which the foreground element is to be synthesized in each of the multiple, distinct synthesized images;
for each of the multiple, distinct synthesized images that are to be generated:
selecting a parameter that is unique to the synthesized image that is to be generated,
selecting, from among multiple pre-determined curve functions that are each associated with displaying foreground elements in synthesized images, a particular curve function based at least on the parameter that is unique to the synthesized image that is to be generated,
generating a curve based on the selected, particular curve function,
dividing the curve into n line segments,
for each of the foreground elements, aligning the foreground element with a starting point of a different line segment,
and
generating a distinct, synthesized image that comprises the background image overlaid within the sub-region by the foreground elements that are each aligned with a starting point of a different line segment; and

providing one or more of the multiple, distinct synthesized images in response to a request for a synthesized image.

2. The method of claim 1 , wherein each foreground element comprises text.

3. The method of claim 1 , wherein each foreground element comprises a foreground image.

4. The method of claim 1 , comprising dividing the background image into sub-regions based on configuration information associated with the foreground elements.

5. The method of claim 1 , comprising processing the foreground elements to be unrecognizable by an automated optical character recognition (OCR) process.

6. The method of claim 1 , wherein aligning the foreground element comprises determining a display shape associated with the foreground element.

7. A non-transitory computer-readable medium storing one or more instructions executable by a computer system to perform operations for providing multiple distinct, synthesized images that each include a same background image and a same foreground element, the operations comprising:
selecting a background image and quantity n foreground elements that are both to be used to generate each of multiple, distinct synthesized images;
selecting a sub-region of the background image in which the foreground element is to be synthesized in each of the multiple, distinct synthesized images;
for each of the multiple, distinct synthesized images that are to be generated:
selecting a parameter that is unique to the synthesized image that is to be generated,
selecting, from among multiple pre-determined curve functions that are each associated with displaying foreground elements in synthesized images, a particular curve function based at least on the parameter that is unique to the synthesized image that is to be generated,
generating a curve based on the selected, particular curve function,
dividing the curve into n line segments,
for each of the foreground elements, aligning the foreground element with a starting point of a different line segment, and
generating a distinct, synthesized image that comprises the background image overlaid within the sub-region by the foreground elements that are each aligned with a starting point of a different line segment; and

providing one or more of the multiple, distinct synthesized images in response to a request for a synthesized image.

8. The non-transitory computer-readable medium of claim 7 , wherein each foreground element comprises text.

9. The non-transitory computer-readable medium of claim 7 , wherein each foreground element comprises a foreground image.

10. The non-transitory computer-readable medium of claim 7 , wherein the operations comprise dividing the background image into sub-regions based on configuration information associated with the foreground elements.

11. The non-transitory computer-readable medium of claim 7 , wherein the operations comprise processing the foreground elements to be unrecognizable by an automated optical character recognition (OCR) process.

12. The non-transitory computer-readable medium of claim 7 , wherein aligning the foreground element comprises determining a display shape associated with the foreground element.

13. A system comprising:
one or more computers; and
one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing instructions, that when executed by the one or more computers, perform operations for providing multiple distinct, synthesized images that each include a same background image and a same foreground element, the operations comprising:
selecting a background image and quantity n foreground elements that are both to be used to generate each of multiple, distinct synthesized images;
selecting a sub-region of the background image in which the foreground element is to be synthesized in each of the multiple, distinct synthesized images;
for each of the multiple, distinct synthesized images that are to be generated:
selecting a parameter that is unique to the synthesized image that is to be generated,
selecting, from among multiple pre-determined curve functions that are each associated with displaying foreground elements in synthesized images, a particular curve function based at least on the parameter that is unique to the synthesized image that is to be generated,
generating a curve based on the selected, particular curve function,
dividing the curve into n line segments,
for each of the foreground elements, aligning the foreground element with a starting point of a different line segment,
and
generating a distinct, synthesized image that comprises the background image overlaid within the sub-region by the foreground elements that are each aligned with a starting point of a different line segment; and

providing one or more of the multiple, distinct synthesized images in response to a request for a synthesized image.

14. The system of claim 13 , wherein each foreground element comprises text.

15. The system of claim 13 , wherein each foreground element comprises a foreground image.

16. The system of claim 13 , wherein the operations comprise dividing the background image into sub-regions based on configuration information associated with the foreground elements.

17. The system of claim 13 , wherein the operations comprise processing the foreground elements to be unrecognizable by an automated optical character recognition (OCR) process.
