1. Which explanation matches map points between image coordinates?A. An affine transform combines linear operations and translation and preserves straight lines and parallelism.B. Images may use smooth interpolation; categorical masks normally use nearest-neighbor interpolation.C. Coordinate transforms map positions between frames with a defined origin and units.D. Registration estimates a transform from corresponding structures, then checks residual displacement.

2. Which explanation matches rotate and warp with an affine transform?A. Coordinate transforms map positions between frames with a defined origin and units.B. An affine transform combines linear operations and translation and preserves straight lines and parallelism.C. Images may use smooth interpolation; categorical masks normally use nearest-neighbor interpolation.D. Registration estimates a transform from corresponding structures, then checks residual displacement.

3. Which explanation matches choose interpolation for images and masks?A. Images may use smooth interpolation; categorical masks normally use nearest-neighbor interpolation.B. Coordinate transforms map positions between frames with a defined origin and units.C. An affine transform combines linear operations and translation and preserves straight lines and parallelism.D. Registration estimates a transform from corresponding structures, then checks residual displacement.

4. For rotate and warp with an affine transform, which result or action fits this practical case: A rotated product image no longer aligns with its inspection mask.A. Write a point as (x, y) in one image, then apply the measured mapping to compare the second.B. Resize a two-class mask and check that every output pixel remains one of the original class IDs.C. Hold out a few matched points to measure the error after alignment.D. Rotate a rectangle and transform each corner to update its annotation.

5. For align two views and check residual error, which result or action fits this practical case: Two views nearly line up, but corners still drift apart.A. Write a point as (x, y) in one image, then apply the measured mapping to compare the second.B. Rotate a rectangle and transform each corner to update its annotation.C. Hold out a few matched points to measure the error after alignment.D. Resize a two-class mask and check that every output pixel remains one of the original class IDs.
