| | ## 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: |
