Cloud-based image improvement

摘要

Approaches are described for managing the processing of image or video data captured by a portable computing device. The device provides a set of images to a remote server executing “in the cloud”. The set of images can include a reference image and at least one other image captured subsequent or prior to the reference. Upon receiving the set of images at the remote server operating, the remote server can process the images to determine a similarity between the reference image and each of the other images. Thereafter, each image having a similarity value above a similarity value threshold can be aligned with the reference image, and the pixel values for corresponding locations in each of the images can be combined to create a processed image. The processed images can be provided to the computing device from the remote server, where the user can decide to accept or discard the image.

主权项

1. A computer implemented method for processing an image, the method comprising:
under control of one or more computer systems configured with executable instructions,
receiving a set of images at a server, the set of images captured by a camera of a computing device in response to an input by a user, the set of images including a reference image, a first image, and a second image, each of the images in the set of images including at least partially overlapping views of an area, the first image and the second image captured within a determined time period of the reference image;determining a first location of a first object represented in each of the reference image, the first image, and the second image;determining a second location of a second object represented in each of the reference image, the first image, and the second image;determining a first similarity value between the reference image and the first image and a second similarity value between the reference image and the second image;determine that the first similarity value and the second similarity value are above a similarity threshold;aligning the first location of the first object represented in first image with the first location of the first object represented in the reference image and the first location of the first object represented in the second image with the first location of the first object represented in the reference image;averaging pixel values for corresponding pixel locations in each of the first image and the second image with the reference image to create a first piecewise aligned image;aligning the second location of the second object represented in first image with the second location of the second object represented in the reference image and the second location of the second object represented in the second image with the second location of the second object represented in the reference image;averaging pixel values for corresponding pixel locations in each of the first image and the second image with the reference image to create a second piecewise aligned image;generating a composite image based at least in part on combining the first piecewise aligned image and the second piecewise aligned image; andsending the composite image to the computing device.
