Matplotlib - Image Display

You have a color image loaded as a NumPy array in BGR format. How do you correctly display it in matplotlib?

AConvert BGR to RGB using array slicing, then use <code>plt.imshow()</code>

BDisplay directly with <code>plt.imshow()</code> without conversion

CConvert BGR to grayscale before displaying

DUse <code>plt.plot()</code> to show the image

Step-by-Step Solution

Solution:

Step 1: Understand color format difference
OpenCV loads images in BGR, but matplotlib expects RGB for correct colors.
Step 2: Convert BGR to RGB
Swap the first and third channels using slicing: img_rgb = img[:,:,::-1].
Step 3: Display with plt.imshow()
Use plt.imshow(img_rgb) to show the image with correct colors.
Final Answer:
Convert BGR to RGB using array slicing, then use plt.imshow() -> Option A
Quick Check:
BGR to RGB conversion = Correct color display [OK]

Quick Trick: Swap BGR channels to RGB before displaying [OK]
