Labeling images for semantic segmentation using Label Studio

The code snippet for this video can be downloaded from:

For labeling your images using Label Studio:

Let us work in Anaconda command prompt. (You can use other command prompts)
Check environments:
conda env list

Create a new environment to install Label Studio:
conda create --name give_some_name pip
(Need to specify pip as a dependency, otherwise it will not be available)

(To specify python version for your env..)
conda create -n give_some_name python=3.7

Now activate the env.
conda activate give_some_name

# Install the Label Studio package
pip install -U label-studio

# Launch it!
label-studio

I checked a bunch of videos and articles on building a custom dataset for a segmentation problem. Your video is by far the clearest, informative, and the most concise for a beginner like me. Other resources I had a bunch of questions after going through, but yours, zero question so far. I will try it out now. Thank you so much!

Brilliant as ever! I have learnt so much about computer vision from this one channel and it has helped me in both academic and professional contexts. I can’t thank you enough for dedicating your time to producing such high quality content.

Sir, you are doing great service to mankind by educating them

Great work! I was searching for the exact thing for my research and this is helping me a lot and saving my time. Your explanation is very clear and informative. Thank you for your time.

Did not expect this tutorial from you, watching and once it is done, will post by a ton for

[markneumann]

Thank you so much. To borrow from Tukey: 'image labeling for the masses'. Like how you bring domain knowledge up front and center.

I did the same work with Paint 3D which are build in Windows :D and saved the result as Tiff image. They will not have bluring edge. But label studio is a more professional tool, classes can be modified and added more easily, Hopefully this will be improved in the future, thank you for sharing this tool, it is very useful indeed. cheers

Your videos are an awesome contribution! Keep it going!

[sudhakumaravel]

thank u, great job, the way u explained every thing is very simple and neat.u are the great motivator for me to do the coding

[HVN-THU-VIEN-CA-NHAN]

Great! This is a useful guide for learning, Thank you very much!

[arods]

Thank you very much. This video was very useful!

The masked images that I exported have different file names from my original images. Is there an option to rename the mask files so that I can map them to the original images? Thanks.

[ianscottuk]

Just a question, as you are working with geospatial data why would you not use qgis for example and create shape files? Is it just more straightforward like this? Great channel btw

[SpaceCat]

For multi-class segmentation, for example 3 as per your video, are we supposed to have 3 different PNG images for each class for that one particular image?

I’m new to this and what I’ve done was give each label a different colour, (blue, red and yellow, and background as black) and exported the mask as a PNG file, in which the resulting mask is just one PNG file with a black background and the 3 colours. Is that a wrong way to do it?

[vimalshrivastava]

Thank you for making such a wonderful informative videos. Which tool support labelling images with tiff format having 4 bands?

[kbo]

Thank you for introducing us to a useful and new tool.
Which of the existing tools or the tools you introduced this time should be used first?

[tirthpatel]

How to deal with the jagged edge in output (during segmentation). I am providing perfect mask for segmentation but still getting jagged edges from my trained model. I am having this issue from long time. Please suggest something. Thank you.

[khadijakhaldi]

Thank you fir the video, so we need to install sqllite before?

[johnnysmith]

Amazing work Sreeni. Kindly show us how to segment colour images trained with patched U-Net.

[MSMML]

I want to use the Json format. Do I need to do changes similar to the binary?. Thanks in advance!!
