Language Python
Transcribed Image Text:**What is the following code doing?**
```python
for x in range(img.getWidth()):
for y in range(img.getHeight() - 1):
pix1 = img.getPixel(x, y)
pix2 = img.getPixel(x, y + 1)
avg1 = pix1.getRGBAverage()
avg2 = pix2.getRGBAverage()
if (abs(avg1 - avg2) < 10):
img.setPixel(x, y, "white")
else:
img.setPixel(x, y, "black")
```
The code iterates through each pixel in an image using nested loops that go through the width (`x`) and height (`y`) of the image. Within these loops, for each pixel `(x, y)`, it compares the pixel with the one directly below it `(x, y+1)`.
- `pix1` and `pix2` represent the current and the next pixel respectively.
- `avg1` and `avg2` are the average RGBA (Red, Green, Blue, Alpha) values of these two pixels.
- The code calculates the absolute difference between these averages.
If the difference is less than 10 (meaning the two pixels are visually similar), the current pixel is set to white. Otherwise, it is set to black.
**Options:**
- Comparing 2 pixels **one on top of the other** and, if they are **similar** make the pixel white, otherwise black
This is the correct description of the code function.
