This is the format of the json file. Here we only put json files for two images, but actually there are more than 40.
I only want to extract values for all_points_x, all_points_y, but I don't know how. The values for all_points_x, all_points_y are included in 1.png896616 (or 2.png810690) -> regions -> shape_attributes.
If there is one image, we extracted all_points_x and all_points_y, but since there are more than two of them, I don't know what to do.
Do I have to extract each image separately?
python json
import json
from os import readlink
with open('json path', 'r') as f:
json_data = json.load(f)
keyList = json_data.keys()
key_list = list(keyList)
#print(key_list)
for e in range(2):
key = key_list[e]
print(key)
for i, j in enumerate(json_data[key]['regions']):
print("all_poins_x : ", i,j['shape_attributes']['all_points_x'])
print("all_poins_y : ", i,j['shape_attributes']['all_points_y'])
That's what I chose. If there is anyone who wants to refer to it, please see!
