Labelimg: Is annotating via labelImg equally applicable with yolo_mark.cmd?

[bit-scientist]

I have some images annotated with this tool and txt format for one image, as you know, is like below:

annotation>
    <folder>pos</folder>
    <filename>02HAT.jpg</filename>
    <path>D:\Projects\hardhat_detection\hardhat-detector\pos\02HAT.jpg</path>
    <source>
        <database>Unknown</database>
    </source>
    <size>
        <width>209</width>
        <height>154</height>
        <depth>3</depth>
    </size>
    <segmented>0</segmented>
    <object>
        <name>helmet</name>
        <pose>Unspecified</pose>
        <truncated>0</truncated>
        <difficult>0</difficult>
        <bndbox>
            <xmin>2</xmin>
            <ymin>4</ymin>
            <xmax>208</xmax>
            <ymax>109</ymax>
        </bndbox>
    </object>
</annotation>

And as it is said here yolo_mark.cmd creates a txt file for one image as:
<object-class> <x> <y> <width> <height>
It is obvious that they are different in form but I thought it might be applicable with former (that's labalImg's) format in some way, because the author (of labelImg) mentions that here

It would save me a great time, thanks!

Are you asking if labelImg can save annotations in the YOLO format? Because your second link explains how to do that...

[bit-scientist]

Yes, but the format in the yolo mark annotator is different as I pointed out!

[vdalv]

I just created an annotation and saved it in the YOLO format, and I got this:
0 0.518182 0.381733 0.775758 0.585480

Which looks exactly like the format you mentioned above:
<object-class> <x> <y> <width> <height>

And looks exactly like the examples that are posted here:
"For example for img1.jpg you will be created img1.txt containing:"

1 0.716797 0.395833 0.216406 0.147222
0 0.687109 0.379167 0.255469 0.158333
1 0.420312 0.395833 0.140625 0.166667

@vdalv Yes, you were right, it saved as you showed. Looks like I mistakenly unnoticed the yolo format was back to PascalVOC when I reopened it. Don't you know any other tool to convert them to yolo by any chance?

[vdalv]

@git-sohib Ah, ok, that makes sense.

I wrote a script to convert all of my PascalVOC xml files to YOLO txt files a little while ago. I just shared the script here: https://gist.github.com/vdalv/321876a7076caaa771d47216f382cba5
