Which processing step is used to create a single panoramic image from multiple adjacent images?

• A. Image stitching
• B. Image fusion
• C. Noise reduction
• D. Histogram analysis

Answer: (A)

The main idea is turning several adjacent photos into one wide view by stitching them together. Image stitching takes overlapping photos, figures out how they relate in space, warps them so they align in a common projection, and blends the edges to hide seams. The goal is a seamless panorama that spans a broader field of view than any individual image.

This is different from image fusion, which combines information from multiple images to improve detail or dynamic range but doesn’t necessarily produce a single aligned panorama. Noise reduction improves each image’s quality by reducing random variation rather than merging multiple shots. Histogram analysis examines brightness distribution in a single image to inform processing, not to create a stitched panorama.
