Attention is used to perform class-specific pooling, which results in a more accurate and robust image classification performance.

Collaborate optimally across the entire value stream – from concept, to planning, to development, to implementation, to operations and ICT infrastructure. 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. U-Net Title. U-Net: Convolutional Networks for Biomedical Image Segmentation. Abstract. There is large consent that successful training of deep networks requires many thousand annotated training samples. The U-net Architecture Fig. 1. U-net architecture (example for 32×32 pixels in the lowest resolution). Each blue box corresponds to a multi-channel feature map. The number of channels is denoted on top of the box. The x-y-size is provided at the lower left edge of the box. White boxes represent copied feature maps. arXivLabs is a framework that allows collaborators to develop and share new arXiv features directly on our website. Both individuals and organizations that work with arXivLabs have embraced and accepted our values of openness, community, excellence, and user data privacy. arXiv is committed to these values and only works with partners that adhere to them. To understand hierarchy of directories based Craps their arguments, see directories structure below. As we see from the example, this network is versatile and can be used for any reasonable image masking task. The number of channels is denoted on top of the box.

As mentioned above, Ciresan et al. The network uses a sliding-window to predict the class label of each pixel by providing a local region patch around that pixel as input.

Limitation of related work:. U-Net has elegant architecture, the expansive path is more or less symmetric to the contracting path, and yields a u-shaped architecture.

Contraction path downsampling Look like a typical CNN architecture, by consecutive stacking two 3x3 convolutions blue arrow followed by a 2x2 max pooling red arrow for downsampling.

At each downsampling step, the number of channels is doubled. Expansion path up-convolution A 2x2 up-convolution green arrow for upsampling and two 3x3 convolutions blue arrow.

At each upsampling step, the number of channels is halved. After each 2x2 up-convolution, a concatenation of feature maps with correspondingly layer from the contracting path grey arrows , to provide localization information from contraction path to expansion path, due to the loss of border pixels in every convolution.

Final layer A 1x1 convolution to map the feature map to the desired number of classes. This dataset contains retina images, and annotated mask of the optical disc and optical cup, for detecting Glaucoma, one of the major cause of blindness in the world.

We need a set of metrics to compare different models, here we have Binary cross-entropy, Dice coefficient and Intersection over Union.

Binary cross-entropy A common metric and loss function for binary classification for measuring the probability of misclassification.

Used together with the Dice coefficient as the loss function for training the model. Dice coefficient.

A common metric measure of overlap between the predicted and the ground truth. This can be achieved by integrating attention gates on top of U-Net architecture, without training additional models.

As a result, attention gates incorporated into U-Net can improve model sensitivity and accuracy to foreground pixels without requiring significant computation overhead.

Attention gates can progressively suppress features responses in irrelevant background regions. Attention gates are implemented before concatenation operation to merge only relevant activations.

Gradients originating from background regions are down-weighted during the backward pass. This allows model parameters in prior layers to be updated based on spatial regions that are relevant to a given task.

To further improve the attention mechanism, Oktay et al. As we see from the example, this network is versatile and can be used for any reasonable image masking task.

If we consider a list of more advanced U-net usage examples we can see some more applied patters:. U-Net is applied to a cell segmentation task in light microscopic images.

This segmentation task is part of the ISBI cell tracking challenge and The dataset PhC-U contains Glioblastoma-astrocytoma U cells on a polyacrylamide substrate recorded by phase contrast microscopy.

The goal of semantic segmentation is the same as traditional image classification in remote sensing, which is usually conducted by applying traditional machine learning techniques such as random forest and maximum likelihood classifier.

Like image classification, there are also two inputs for semantic segmentation. In this guide, we will mainly focus on U-net which is one of the most well-recogonized image segmentation algorithms and many of the ideas are shared among other algorithms.

To follow the guide below, we assume that you have some basic understanding of the convolutional neural networks CNN concept. U-net was originally invented and first used for biomedical image segmentation.

Its architecture can be broadly thought of as an encoder network followed by a decoder network. Unlike classification where the end result of the the deep network is the only important thing, semantic segmentation not only requires discrimination at pixel level but also a mechanism to project the discriminative features learnt at different stages of the encoder onto the pixel space.
