Abstract

A digital magazine server presents content retrieved from various sources to a user. The content may include various images, with images selected by the digital magazine server for presentation to a user along with additional content. Text associated with an image may also be retrieved and presented to the user along with the image. To improve presentation of images with text, the digital magazine server identifies features in an image and identifies regions of the image where text is capable of being presented without obscuring or being obscured by features of the image. The image is modified to present text associated with the image in one or more of the identified images, allowing the text to be presented without detracting from features of the image.

the location of the region relative to one or more boundaries of the image, a description of a shape of the region, a description of one or more dimensions of the region, and any combination thereof.

8. The method of claim 6 wherein the identifier corresponding to the region associates the region with the image.

9. The method of claim 1, wherein selecting text for presentation along with the image further comprises:

identifying text associated with the image; and

retrieving the identified text for presentation along with the image.

10. The method of claim 1, wherein selecting one or more of the one or more regions in the image capable of including text comprises:

identifying text associated with the image;

identifying one or more portion of the identified text, each portion of the identified text associated with one or more attributes; and

selecting a region in the image capable of including text in which a portion of the identified text is presented based at least in part on one or more of the attributes associated with the portion of the identified text.

11. A method comprising:

obtaining an image for presentation to a user of a digital magazine server;

identifying one or more features of the image, the features identifying regions containing one or more objects included in the image;

identifying one or more regions in the image capable of including text based at least in part on the one or more identified features, a region in the image capable of including text having at least a threshold distance from an identified feature;

selecting text for presentation along with the image;

selecting one or more of the one or more regions in the image capable of including text;

modifying the image to present the selected text in the one or more selected regions in the image capable of including text; and

displaying the modified image to the user of the digital magazine sever.

12. The method of claim 11, wherein selecting one or more of the one or more regions in the image capable of including text further comprises:

identifying an image template including region for presenting text having at least a threshold similarity to at least a threshold number of the one or more identified regions capable of presenting text;

selecting one or more regions for presenting text in the identified image template for presenting text; and

identifying regions in the image capable of including text based on locations associated with the selected one or more regions for presenting text in the identified image template.

13. The method of claim 11, wherein selecting one or more of the one or more regions in the image capable of including text further comprises:

identifying an image template including region for presenting text having at least a threshold similarity to at least a threshold number of the one or more identified regions capable of presenting text;

selecting one or more regions for presenting text in the identified image template for presenting text based at least in part on location information associated with the regions for presenting text in the identified image template identifying positions of the regions for presenting text relative to one or more boundaries of the identified image template; and

identifying regions in the image capable of including text based on locations associated with the selected one or more regions for presenting text in the identified image template.

14. The method of claim 11, wherein selecting one or more of the one or more regions in the image capable of including text further comprises:

identifying one or more portions of the selected text for presentation in a region in the image capable of including text based at least in part on characteristics of the region in the image capable of including text; and

associating the one or more portions of the selected text with the region in the image capable of including text.

15. The method of claim 11, wherein modifying the image to present the selected text in the one or more selected regions in the image capable of including text further comprises:

identifying one or more locations of the image corresponding to each of the one or more selected regions in the image; and

overlaying the selected text in the identified one or more locations of the image.
