U Net How to Get Best Site Performance
a recent GPU. The full implementation (based on Caffe) and the trained networks are available at. domainsecurity.conet. Fully convolutional neural networks like U-Net have been the state-of-the-art methods in medical image segmentation. Practically, a network is highly. Abstract: U-Net is a generic deep-learning solution for frequently occurring quantification tasks such as cell detection and shape measurements in biomedical. In this work, we firstly modify the U-Net with functional blocks aiming to pursue higher performance. The absence of the expected performance.

I am trying to implement U-NET segmentation on Kaggle Nuclei segmentation data. The training data set contains images with masks in such a way that.

There are many applications of U-Net in biomedical image segmentation , such as brain image segmentation ''BRATS''  and liver image segmentation "siliver07" .
Variations of the U-Net have also been applied for medical image reconstruction. The basic articles on the system     have been cited , , and 22 times respectively on Google Scholar as of December 24, From Wikipedia, the free encyclopedia.

These activities involve quantitative diagnosis. If we can make it automatic, cost can be saved with even higher accuracy. The U-net architecture is as shown above.
It consists of contraction path and expansion path. Contraction path. Expansion path. Since unpadded convolution is used, output size is smaller than input size.
Instead of downsizing before network and upsampling after network, overlap tile strategy is used. Thereby, the whole image is predicted part by part as in the figure above.
The yellow area in the image is predicted using the blue area. At the image boundary, image is extrapolated by mirroring.
Since the training set can only be annotated by experts, the training set is small. To increase the size of training set, data augmentation is done by randomly deformed the input image and output segmentation map.
Since the touching objects are closely placed each other, they are easily merged by the network, to separate them, a weight map is applied to the output of network.
To compute the weight map as above, d1 x is the distance to the nearest cell border at position x, d2 x is the distance to the second nearest cell border.
Thus, at the border, weight is much higher as in the figure. Thus, the cross entropy function is penalized at each position by the weight map.
And it help to force the network to learn the small separation borders between touching cells. U-Net got the highest IoU for these two datasets.
At the Overlap Tile Strategy, zero padding is used instead of mirroring at the image boundary.
