What does image interpolation do when resizing an image using scipy.ndimage.zoom?

AIt deletes pixels randomly to reduce image size.

BIt estimates new pixel values to make the resized image smooth.

CIt converts the image to grayscale automatically.

DIt changes the image format to JPEG.

Step-by-Step Solution

Solution:

Step 1: Understand image resizing
When resizing, new pixels must be created or removed to fit the new size.
Step 2: Role of interpolation
Interpolation estimates these new pixel values to keep the image smooth and avoid blockiness.
Final Answer:
It estimates new pixel values to make the resized image smooth. -> Option B
Quick Check:
Image interpolation = smooth pixel estimation [OK]

Quick Trick: Interpolation fills new pixels smoothly when resizing images [OK]
