Abstract

Methods and systems are presented for automatically generating a slide associated with a slideshow. In one aspect, a method includes selecting an image for inclusion in a slideshow, where the image has associated facial detection information. A face location is determined in the selected image based on the facial detection information and the selected image is cropped based on the determined face location to generate a cropped image depicting the included face. The cropped image is inserted into a slide associated with the slideshow. Further, an animation having a defined animation path can be associated with the slide. Also, the face location can be identified as a position in the animation path and the slide can be animated based on the associated animation.

Claims

1. A computer-implemented method of generating a slide, the method comprising:

selecting an image for inclusion in a slideshow, the image having associated facial detection information;

determining a face location in the selected image based on the facial detection information;

cropping the selected image based on the determined face location to generate a cropped image depicting the included face; and

inserting the cropped image into a slide associated with the slideshow.

2. The computer-implemented method of claim 1, wherein selecting an image further comprises:

determining that the image corresponds to a subject of the slideshow.

3. The computer-implemented method of claim 1, further comprising:

determining a slide layout based on dimensions corresponding to the cropped image.

4. The computer-implemented method of claim 1, further comprising:

identifying a drop-zone included in the slide; and

associating the cropped image with the identified drop-zone.

5. The computer-implemented method of claim 4, further comprising:

determining one or more drop-zone dimensions; and

generating the cropped image in accordance with the determined one or more drop-zone dimensions.

6. The computer-implemented method of claim 1, wherein cropping the selected image further comprises:

defining a crop region such that the included face is positioned near a center of the cropped image.

7. The computer-implemented method of claim 1, further comprising:

associating an animation with the slide, the animation having a defined animation path;

identifying the face location as a position in the animation path; and

animating the slide based on the associated animation.

8. A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

selecting an image for inclusion in a slideshow, the image having associated facial detection information;

determining, based on the facial detection information, a face region in the selected image that includes one or more faces;

selecting a slide layout based on the determined face region; and

generating a slide associated with the slideshow based on the selected image and the selected slide layout.

9. The computer program product of claim 8, wherein selecting an image further comprises:

determining that the image corresponds to a subject of the slideshow.

10. The computer program product of claim 8, further operable to cause data processing apparatus to perform operations comprising:

cropping the selected image based on the determined face region.

11. The computer program product of claim 10, further operable to cause data processing apparatus to perform operations comprising:

identifying a drop-zone included in the slide; and

associating the cropped image with the identified drop-zone.

12. The computer program product of claim 8, further operable to cause data processing apparatus to perform operations comprising:

generating the slide such that the face region is aligned with a center of a display area.

13. The computer program product of claim 8, further operable to cause data processing apparatus to perform operations comprising:

associating an animation with the slide, the animation having a defined animation path;

identifying the face region as a position in the animation path; and

animating the slide based on the associated animation.

14. A computer-implemented method of animating a slide, the method comprising:

inserting an image into a slide, the image having associated facial detection information;

analyzing the facial detection information to determine a location of an included face;

selecting an animation style;

defining an animation path based on the selected animation style, wherein a point in the animation path corresponds to the location of the included face; and

animating the slide in accordance with the defined animation path.

15. The computer-implemented method of claim 14, wherein selecting an animation style further comprises:

excluding an animation style associated with a preceding slide.

16. The computer-implemented method of claim 14, further comprising:

determining a layout of the slide based on one or more dimensions of the image.

17. The computer-implemented method of claim 14, further comprising:

identifying a location of a second included face in the image; and

configuring the location of the second face as a second point in the animation path.

18. The computer-implemented method of claim 14, further comprising:

selecting the included face as a point in the animation path based on a number of occurrences of the included face in an image collection.

19. A computer program product, encoded on a computer-readable medium, operable to cause data processing apparatus to perform operations comprising:

inserting an image into a slide, the image having associated facial detection information;

analyzing the facial detection information to determine a location of an included face;

selecting an animation style;

defining an animation path based on the selected animation style, wherein a point in the animation path corresponds to the location of the included face; and

animating the slide in accordance with the defined animation path.

20. The computer program product of claim 19, further operable to cause data processing apparatus to perform operations comprising:

selecting the animation style based on the facial detection information.

21. The computer program product of claim 19, further operable to cause data processing apparatus to perform operations comprising:

determining a layout of the slide based on one or more dimensions of the image.

22. The computer program product of claim 19, further operable to cause data processing apparatus to perform operations comprising:

identifying a location of a second included face in the image; and

configuring the location of the second face as a second point in the animation path.

23. The computer program product of claim 19, further operable to cause data processing apparatus to perform operations comprising:

selecting the included face as a point in the animation path based on one or more dimensions of the included face.

24. A system comprising:

a computer-readable medium storage an image collection and a plurality of slide layouts; and

a computing system including processor electronics configured to perform operations comprising;

selecting an image from the image collection, the image having associated facial detection information;

determining, based on the facial detection information, a face region in the selected image that includes one or more faces;

selecting one of the plurality of slide layouts based on the determined face region; and

generating a slideshow slide based on the selected image and the selected slide layout.
