Methods, systems, and media for image processing using hierarchical expansion are provided. More particularly, the hierarchical expansion can include a merge expansion and/or a refine expansion. In some embodiments, a method for image processing, comprising: receiving a plurality of images, wherein each of the plurality of images has one of a plurality of resolutions; for a first image from the plurality of images that has a first resolution, determining a first set of labels corresponding to each pixel of the first image; and for a second image from the plurality of images that has a second resolution, generating a second set of labels corresponding to each pixel of the second image based on the first set of labels. |

1. A method for image processing, the method comprising:
receiving, using a hardware processor, a plurality of images, wherein each of the plurality of images has one of a plurality of resolutions; for a first image from the plurality of images that has a first resolution, determining, using the hardware processor, a first set of labels corresponding to each pixel of the first image; and for a second image from the plurality of images that has a second resolution, generating, using the hardware processor, a second set of labels corresponding to each pixel of the second image based on the first set of labels by:
(a) scaling, using the hardware processor, the first set of labels to generate a set of scaled labels;(b) determining, using the hardware processor, a set of proposed labels for each pixel of the second image based on the set of scaled labels;(c) generating, using the hardware processor, a probability score for each proposed label in the set of proposed labels;(d) selecting, using the hardware processor, a proposed label from the set of proposed labels based at least in part on the probability score; and(e) determining, using the hardware processor, whether to assign the proposed label for each pixel to the second set of labels of the second image. |
