## Code snippet to visualise the position of the box |
|
|
|
```python |
|
import matplotlib.image as img |
|
import matplotlib.pyplot as plt |
|
from datasets import load_dataset |
|
from matplotlib.patches import Rectangle |
|
|
|
# Load dataset |
|
ds_name = "SaulLu/Caltech-101" |
|
ds_config = "without_background_category" |
|
|
|
ds_without = load_dataset(ds_name, ds_config, use_auth_token=True) |
|
|
|
# Extract information for the sample we want to show |
|
index = 100 |
|
sample = ds_without["train"][index] |
|
box_coord = sample["annotation"]["box_coord"][0] |
|
img_path = sample["image"].filename |
|
|
|
# Create plot |
|
# define Matplotlib figure and axis |
|
fig, ax = plt.subplots() |
|
|
|
# plot figure |
|
image = img.imread(img_path) |
|
ax.imshow(image) |
|
|
|
# add rectangle to plot |
|
ax.add_patch( |
|
Rectangle((box_coord[2], box_coord[0]), box_coord[3] - box_coord[2], box_coord[1] - box_coord[0], fill=None) |
|
) |
|
|
|
# display plot |
|
plt.show() |
|
``` |
|
