model for greyscale images? #53
Comments
Hi @dschneiderch,
The models have been trained on RGB images, so colour information certainly plays a role for the model prediction. I don't think it will work well on singlechannel images.
The pipeline fetches the pretrained models from this Zenodo record, which doesn't seem to be very reliable for that purpose. I need to upload them somewhere else and update the pipeline. In the meantime, you can either try again (it will work eventually) or change back to the dropbox links (see f7566a0) |
do you think it would be possible to train a similar model with grayscale images or does imagenet+ rely on color info too? |
It should be possible, although the input layer of the model needs to be changed to work with 1-channel images. I think the main problem is that the pretrained weights in DeepLabV3+ are obtained by pretraining on the ImageNet dataset which also consists of RGB images. A better way would be to convert the whole ImageNet dataset to grayscale and train on that, but that is probably not feasible because of the hardware requirements that come with it. |
No I don't. Fluorescence imaging is an interesting topic, but we currently don't have a camera for that. |
Hi @phue,
the segmentation worked great on the first dataset after I sorted out the docker storage issue. Next I tried to run model A on some greyscale images - is that possible or do the models depend on shape and color differences?
I got this error which wasn't clear to me if it was related and i couldnt find a
