Method and system for high accuracy and reliability registration of multi modal imagery

摘要

A method for mapping a target image to a reference image includes receiving a target image; receiving a reference image that overlaps the target image; preprocessing the target image, wherein the preprocessing includes: rejecting a target image with a shadow region above a shadow threshold while keeping a target image with a shadow region below a shadow threshold; providing an uncertainty in a location of the kept target image relative to the reference image; transforming the kept target image to an atlas projection to match the reference image; partitioning the transformed kept target image into a sub-region; and determining a matching statistic for each sub-region to determine a location for each sub-region relative to the reference image.

1. A non-transitory computer-readable storage medium having instructions stored therein, the instructions executable by a processor to cause the processor to perform operations comprising:
receiving a plurality of target images; receiving a reference image that overlaps the plurality of target images; preprocessing the plurality of target images, wherein the preprocessing includes:
rejecting one or more first target images of the plurality of target images with a shadow region above a shadow threshold while keeping one or more second target images of the plurality of target images with a shadow region below the shadow threshold;for each second target image:
transforming the second target image into an atlas projection to match the reference image; andpartitioning the transformed target image into a plurality of sub-regions; determining a matching statistic for each sub-region to determine a location for each sub-region relative to a corresponding portion of the reference image; and determining an alignment of each sub-region with the corresponding portion of the reference image based on the determined matching statistic for each sub-region.
