CV2 save image with keypoint-CodePudding

Is there a way to save an image with the keypoints overlaid?

eg. after using blob detection i get this image:

Is there a way to save this image such that when loaded it has the red circles overlaid. for example something along the lines of

cv2.saveWindow("CountedImage.png", window)

where CountedImage.png has the red circles overlaid.

CodePudding user response：

After you do your Blob Detection you can simply do something like:

import cv2

"""
   Your blob detection code
"""

cv2.imshow("Blob Detected ", result_image)
cv2.waitKey(0)

# Save the result figure
cv2.imwrite('result.png',result_image)

cv2.destroyAllWindows()
