Question: How to delete a certain label in the json file generated by the labelme label?
Here is an example to delete a point:
After opening the labelme and opening the json file, as shown in the figure:
Click [Edit] -> [Edit Polygons] in the upper left corner:
Then find the label corresponding to the point in the [Polygon Labels] on the right. The method is to click the label name in [Polygon Labels] with the same color as the point according to the color of the point, and the corresponding label will be marked in the picture. The points can be tried one by one until they are found. Or click the checkmark in the box in front of the label. If the label is not checked, the point corresponding to the label will disappear.
After finding the label corresponding to the point, directly locate the label with the mouse, right-click [Delete Polygons] -> [yes], and then click [Save] on the left to save.
If you are not sure whether the deletion was successful, you can open the json file again to check it.
