## Example Usage (Python)

Below is a minimal example that loads an image, converts it to grayscale, and saves the output.

```python
import cv2

img = cv2.imread("input.jpg")
if img is None:
raise FileNotFoundError("Could not read input.jpg")

gray = cv2.cvtColor(img, cv2.COLOR_BGR2GRAY)
cv2.imwrite("output_gray.jpg", gray)
print("Saved output_gray.jpg")
