Question

3 order the images from lowest to highest gradient.
1.
2.
3.

Explanation:

Image gradient measures the change in pixel intensity across an image. The lowest gradient has the most uniform intensity (no sharp changes), the middle has moderate intensity variation, and the highest has the most distinct, sharp intensity differences.

1. The bottom image has the most uniform, consistent pixel intensity, so it has the lowest gradient.
2. The middle image has gradual intensity change plus a few distinct points, giving it a moderate gradient.
3. The top image has sharp, high-contrast differences between the dark blue dots and light blue background, so it has the highest gradient.

Answer:

1. Bottom image (uniform light blue pattern)
2. Middle image (gradient blue with sparse dots)
3. Top image (dark blue dots on light blue background)
