COCO JSON- import custom attributes

[alelordelo]

Hi Ryo,

How can I import custom attributes from COCO JSON?

"image_id": 11342, "category_id": 20, "area": 3000 * 4000, "bbox": [0, 0, 3000, 4000],
"iscrowd": 0, "color": "black" # new attribute

I have a very large dataset, and manually updating attributes on RectLabel is not viable.

Is there a way to do it?

I thought of running a python script to update the rectLabel XML files (from my COCO JSON), but the created attributes fields on RectLabel are not there

Still cannot import any custom attributes from COCO JSON... Maybe with LabelMe JSON is possible?

You can create a color attribute and combine with object names. https://rectlabel.com/settings#attributes

This is an example of the COCO JSON file. Please import from App menu -> Import settings file.

Thanks Ryo!

Multiple select works now.

But Text input is not working…

Is the structure bellow correct?

{ "name": "camera orientation", "type": "Multiple select", "items": ["back view", "frontal view", "left view", "right view"] }, { "name": "photo style", "type": "Multiple select", "items": ["photograph", "portrait"] }, { "name": "gender", "type": "Multiple select", "items": ["woman", "men"] }, { "name": "shot prompt", "type": "Text input", "input": "default" # new initial value }

Thanks for your feedback. For the text input, at this moment, there is not the default text setting. The default text is empty. Please let us know your opinion.

The attribute types are "Single select", "Multiple select", and "Text input". https://rectlabel.com/settings#attributes

We think for the gender, you can use the "Single select".
