drawing segmentation points on png images

[senemaktas]

Hello,
Thank you for the dataset. I have download the dataset, annotations, masks, images.

I am trying to write points to images in png format by taking points from annotations json files.
However, I cannot see the "points" on the image. (segmentation points).

How can i draw segmentations points on png images? Aren't the "points" specified in json files segmentation points?

The piece of code I use is as follows:

      xyz_points = each_element["points"]
      # get x and y as integer
      xy_points = [[int(each[:2][0]), int(each[:2][1])] for each in xyz_points]
      # drawing
      pts = np.array(xy_points, np.int32)
      pts = pts.reshape((-1, 1, 2))
      cv2.polylines(img, [pts], isClosed=True, color=(0, 255, 0), thickness=80)
      cv2.drawContours(img, pts, -1, (0, 255, 0), 80)

Sample image and json matches:
