U-net for image segmentation

I was wondering if it is possible to download U-net (https://lmb.informatik.uni-freiburg.de/people/ronneber/u-net/) for use as a pretrained convolutional neural network for Matlab for medical image segmentation.

Hi Joseph Stember, did you get U-net downloaded and working in Matlab?

[HARADHAN CHEL]

In matlab documentation, it is clearly written how to build and train a U-net network when the input image and corresponding labelled images are stored into two different folders. But Surprisingly it is not described how to test an image for segmentation on the trained network. For testing images, which command we need to use? is it semanticseg? . Unfortunately this method is not working and not producing any result.

I think you can look at this one: https://www.mathworks.com/matlabcentral/answers/uploaded_files/107430/createUnet.m

This is a function I found online by mathworks for a modified version U net, I reproduced my own implementation of U net referring to this function so I could make other versions.

i still suffer from how to write a matlab code by convolutional neural network for segmentation image

[Yan Ma]

HI Moucheng, I have downloaded the code from the Internet.It generated a U-net network.I want to know how can I ues the LayerGraph to train the dataset?

Hi Moucheng Xu,

Is it this code can run in Matlab?

Hi Joseph,

According to the documentation of u-net, you can download the ready trained network, the source code, the matlab binaries of the modified caffe network, all essential third party libraries and the matlab-interface for overlap-tile segmentation. Best bet would be to use the same setup as recommended by u-net, i.e. Ubuntu Linux 14.04 and Matlab 2014b (x64).

You might also find of interest the image segmentation functionality in the Image Processing Toolbox:

Hope this helps!

Hi Kris, Has this changed with the 2017b or 2018a release?

Hi Chris,

I want to apply UNet to segment weed plants, how can I label the images?

The network you pointed to was trained in Caffe. You can use importCaffeNetwork to import this pretrained U-Net network:
