To further improve the attention mechanism, Oktay et al. By implementing grid-based gating, the gating signal is not a single global vector for all image pixels, but a grid signal conditioned to image spatial information.
The gating signal for each skip connection aggregates image features from multiple imaging scales. By using grid-based gating, this allows attention coefficients to be more specific to local regions as it increases the grid-resolution of the query signal.
This achieves better performance compared to gating based on a global feature vector. Additive soft attention is used in the sentence to sentence translation Bahdanau et al.
This tiling strategy is important to apply the network to large images, since otherwise the resolution would be limited by the GPU memory.
The network consists of a contracting path and an expansive path, which gives it the u-shaped architecture. The contracting path is a typical convolutional network that consists of repeated application of convolutions , each followed by a rectified linear unit ReLU and a max pooling operation.
During the contraction, the spatial information is reduced while feature information is increased. The expansive pathway combines the feature and spatial information through a sequence of up-convolutions and concatenations with high-resolution features from the contracting path.
There are many applications of U-Net in biomedical image segmentation , such as brain image segmentation ''BRATS''  and liver image segmentation "siliver07" .

To optimize this model as well as subsequent U-Net implementation for comparison, training over 50 epochs, with Adam optimizer with a learning rate of 1e-4, and Step LR with 0.
The loss function is a combination of Binary cross-entropy and Dice coefficient. The model completed training in 11m 33s, each epoch took about 14 seconds.
A total of 34,, trainable parameters. The epoch with the best performance is epoch 36 out of Test the model with a few unseen samples, to predict optical disc red and optical cup yellow.
From these test samples, the results are pretty good. I chose the first image because it has an interesting edge along the top left, there is a misclassification there.
The second image is a little dark, but there are no issues getting the segments. U-Net architecture is great for biomedical image segmentation, achieves very good performance despite using only using 50 images to train and has a very reasonable training time.
And on Attention U-Net:. Follow me on Medium or connect with me on LinkedIn. Moreover, the network is fast. The network architecture is illustrated in Figure 1.
It consists of a contracting path left side and an expansive path right side. The contracting path follows the typical architecture of a convolutional network.Let’s now look at the U-Net with a Factory Production Line analogy as in fig We can think of this whole architecture as a factory line where the Black dots represents assembly stations and the path itself is a conveyor belt where different actions take place to the Image on the conveyor belt depending on whether the conveyor belt is Yellow.

The x-y-size is provided at the lower left edge of the box. White boxes represent copied feature maps. The arrows denote the di erent operations. as input. Download. We provide the u-net for download in the following archive: simplyjavea.com (MB). It contains the ready trained network, the source code, the matlab binaries of the modified caffe network, all essential third party libraries, the matlab-interface for overlap-tile segmentation and a greedy tracking algorithm used for our submission for the ISBI cell tracking.
