Use labelme with iris dataset and yolo darknet

[abdou31]

Hello Sir, I want to know how can i use this tool with iris dataset (custom dataset ) and also with yolo darknet? Thanks

[wkentaro]

I don’t know much about iris dataset (is it a flower dataset?). But what you need to do is annotate image with polygon or bounding box.

To use annotated data, you need to create a script equivalent to labelme2voc.py and labelme2coco.py (e.g., labelme2darknet.py).

Iris data means the dataset of iris region in the eye , i worked on this to loacte the iris region and i use darknet yolo forked by AlexayAB , the annotation of dataset e.g CASIA with four values giving box , I don't need drawing box on iris , i need to draw the form of the region of iris ( not always circle ) , so for that reason , i choose to use the segmentation method to do that

[wkentaro]

Ok then, what is you're question?

[abdou31]

My question is : Is it possible to labelling iris data using Labelme tool ? Do you know how to do that? ( just give an exemple )

Is it possible to labelling iris data using Labelme tool ?

You can just annotate an image with polygons (or bounding boxes), right? As demonstrated in README: https://github.com/wkentaro/labelme#description.

Why do you think it may be not possible?

[abdou31]

For example this image: I want to annotate the iris region in the eye using segmentation , did you understand me now? https://i.imgur.com/YBxcg0s.jpg

[wkentaro]

Yeah. You can annotate iris with polygon annotations.

Actually, I'm still not sure what you're asking..

[abdou31]

My question is clear , that is how to do segmentation with object or with iris region ?

[wkentaro]

Are you asking about how to use machine learning method for object segmentation?

If so, you should read paper or ask people on forum. Here is not the place it supposed to be. This repo is about human manual annotation, not how to use learning method for segmentation.

[abdou31]

Sorry , I mean annotate segmentation with iris regions ?

[wkentaro]

You want manually annotate the region of an iris in an image?

If so, you can use the polygon annotation of labelme as I said before.

[abdou31]

yes using segmentation ( coloring the region of iris ) with your tool

[wkentaro]

Ok. Please use polygonal annotation of this tool.

[abdou31]

Ok thanks , can you give me instruction beacause i dont find segmentation option?

[wkentaro]

Have you read the tutorial? https://github.com/wkentaro/labelme/blob/master/examples/tutorial/README.md

[abdou31]

I read just the main page of the github tool's

[wkentaro]

I’m just not sure why you need instruction.

[wkentaro]

I don’t have anything to explain more aside from the readme.

[abdou31]

I need instruction because i don't understand how to use segmentation to labelling the region of iris (images)

[wkentaro]

What have you tried and what you don’t understand about this tool?

[abdou31]

I have tried using keypoints to labelling image and i dont understand how to use this segmentation after that , Note: I will read the instructions Thanks ,

[wkentaro]

It's out of the scope of this repo, right? This repo is for annotations not how-to-use-annotations.

Maybe you should check state-of-the-art segmentation or detection system (e.g., YOLO, PSPNet, Mask R-CNN etc.), and check how to use polygonal annotation on that system. There are some common formats of export (e.g., COCO, VOC) that are already included in this repo. So if you can use it, use it. If not, maybe this repo is not helpful for you.
