Patent Images

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.
