您可以使用以下代码将COCO格式数据集的分割信息展示在相应的图片上:
```
import numpy as np
import cv2
from pycocotools.coco import COCO
# Load the COCO dataset
coco = COCO('path/to/annotations.json')
# Get the IDs of all images in the dataset
img_ids = coco.getImgIds()
# Loop over all images
for img_id in img_ids:
# Load the image
img = coco.loadImgs(img_id)[0]
img_path = 'path/to/images/' + img['file_name']
img = cv2.imread(img_path)
# Get the annotations for the current image
ann_ids = coco.getAnnIds(imgIds=img_id)
anns = coco.loadAnns(ann_ids)
# Loop over all annotations and draw the segmentation masks on the image
for ann in anns:
mask = coco.annToMask(ann)
color = [np.random.randint(0, 255) for _ in range(3)]
img[mask == 1] = color
# Display the image
cv2.imshow('image', img)
cv2.waitKey(0)
```
此代码将显示每个图像及其对应的分割掩模。
