This table contains the mapping information to correlate images of the same object via linear affine transformations. The mapping may only invlove a portion of either image as defined in the region_on_imageX columns.

SQE_image.sqe_image_id fk_image1_to_image_idR

Id of the first SQE_image to be mapped.

image2_id INT UNSIGNED 10 0
SQE_image.sqe_image_id fk_image2_to_image_idR

Id of the second SQE_image to be mapped.

region_on_image1 POLYGON 0 null

Region on image 1 that can be found in image 2.

region_on_image2 POLYGON 0 null

Region in image 2 that can be found in image 1.

transform_matrix VARCHAR 255 '{"matrix":[[1,0,0],[0,1,0]]}'

Linear affine transform to apply to image 2 in order to align it with image 1. The format is: “{“matrix”: [[sx cosθ, -sy sinθ, tx],[sx sinθ, sy cosθ, ty]]}”.

[[sx cosθ, -sy sinθ, tx]: ./../null
[sx sinθ, sy cosθ, ty]: ./../null

region1_hash BINARY 128 NULL


region2_hash BINARY 128 NULL

Polygon hash for uniqueness constraints.
