Detecting Motion in Images

A computer-implemented method, comprising:

• receiving, by a computing system, a sequence of images that includes a first image and a second image, in addition to multiple other images that were captured by a camera as part of the sequence of images, wherein a position of the camera when the first image was captured is different from a position of the camera when the second image was captured with respect to a scene that is reflected in the first image and the second image;
• generating, by the computing system, a modified version of the first image that presents the scene as depicted in the first image from a position of the camera when the second image was captured;
• determining, by the computing system, a level of movement in the scene between when the first image was captured and when the second image was captured based on a comparison of the modified version of the first image to the second image;
• and
• determining, by the computing system and based on having determined that the level of movement in the scene between when the first image was captured and when the second image was captured satisfies criteria, to:
• (i) maintain the first image or the second image in computer storage, at least until user input removes the first image or the second image from the computer storage, and
• (ii) remove at least one image of the multiple other images that were captured by the camera as part of the sequence of images from the computer storage, without receipt of user input that specifies that the at least one image is to be removed from the computer storage.

One or more non-transitory computer-readable devices including instructions that, when executed by one or more processors, cause performance of operations that include:

• receiving, by a computing system, a sequence of images that includes a first image and a second image, in addition to multiple other images that were captured by a camera as part of the sequence of images, wherein a position of the camera when the first image was captured is different from a position of the camera when the second image was captured with respect to a scene that is reflected in the first image and the second image;
• generating, by the computing system, a modified version of the first image that presents the scene as depicted in the first image from a position of the camera when the second image was captured;
• determining, by the computing system, a level of movement in the scene between when the first image was captured and when the second image was captured based on a comparison of the modified version of the first image to the second image;
• and
• determining, by the computing system and based on having determined that the level of movement in the scene between when the first image was captured and when the second image was captured satisfies criteria, to:
• (i) maintain the first image or the second image in computer storage, at least until user input removes the first image or the second image from the computer storage, and
• (ii) remove at least one image of the multiple other images that were captured by the camera as part of the sequence of images from the computer storage, without receipt of user input that specifies that the at least one image is to be removed from the computer storage.
