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.

excluding an animation style associated with a preceding slide.

14. The computer-implemented method of claim 12, further comprising:

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

15. The computer-implemented method of claim 12, 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.

16. A computer program product, encoded on a non-transitory computer-readable storage device, operable to cause data processing apparatus to perform operations comprising:
