Segmentation mask image is three color channel

Question

Segmentation mask image is three color channel

prajachintya opened this issue 2 years ago · 8 comments

Hi,

I've tried to export images to Segmentation Mask in CVAT, but it came out as three color channel image. How can I get the single-channel mask images?

Thank you :)

Hi,
Unfortunately, CVAT doesn't give you ID maps. I suggest using color2id.py. Just config the labels_info.json based on your own labels list.

Good luck!

Thank you for the reply. This algorithm works fine. Btw how did you do the evaluation for the prediction results?

Hi, Sorry I was a little busy this week, I'll add argparse package to color2id.py to be easier to work with it. Regarding your second question, you can use compute_iou.py. Again, please configure the labels_info.json for this code.

Good Luck!

Thank you!

No worries; thanks for the update! By the way, for the AquaNet code, I'm wondering why the number of classes is subtracted by 17? [image: image.png] Thank you! *Best Regards,* *Praja*

According to the manuscript of the paper, "The aquatic path is to segment different types of waterbodies including sea, river, waterfall, wetland and etc., while the non-aquatic path is to segment other categories such as ship and bridge." The manuscript explains further that "Aquatic categories include 17 labels showing just water content in different forms and bodies, e.g., sea, river, lake, etc."

Hope it helps.

Thank you for your explanation! I applied PSPNet and AquaNet to 7 classes dataset. One class is for water and the rest 6 classes are non water classes. However the results look like they were reversed. Is self indices order on AquaNet shows specific purpose? I wondering why the self indices shows are not in order. Have a great day!

Yes! AQUANet is customized for ATLANTIS. I would modify the self.indices based on the new dataset.
