| ## 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() |
| ``` |
|
|
| Result: |
