M2MRF: Many-to-Many Reassembly of Features for Tiny Lesion Segmentation in Fundus Images

  title={M2MRF: Many-to-Many Reassembly of Features for Tiny Lesion Segmentation in Fundus Images},
  author={Qing Liu and Haotian Liu and Yixiong Liang},
Feature reassembly is an essential component in modern CNN-based segmentation approaches, which includes feature downsampling and upsampling operators. Existing operators reassemble multiple features from a small predefined region into one for each target location independently. This may result in loss of spatial information, which could vanish activations caused by tiny lesions particularly when they cluster together. In this paper, we propose a many-to-many reassembly of features (M2MRF). It… 


V-Net: Fully Convolutional Neural Networks for Volumetric Medical Image Segmentation
This work proposes an approach to 3D image segmentation based on a volumetric, fully convolutional, neural network, trained end-to-end on MRI volumes depicting prostate, and learns to predict segmentation for the whole volume at once.

UNet++: Redesigning Skip Connections to Exploit Multiscale Features in Image Segmentation
UNet++ is proposed, a new neural architecture for semantic and instance segmentation by alleviating the unknown network depth with an efficient ensemble of U-Nets of varying depths and redesigning skip connections to aggregate features of varying semantic scales at the decoder sub-networks, leading to a highly flexible feature fusion scheme.
U-Net: Convolutional Networks for Biomedical Image Segmentation
It is shown that such a network can be trained end-to-end from very few images and outperforms the prior best method (a sliding-window convolutional network) on the ISBI challenge for segmentation of neuronal structures in electron microscopic stacks.
CARAFE: Content-Aware ReAssembly of FEatures

HED performs image-to-image prediction by means of a deep learning model that leverages fully convolutional neural networks and deeply-supervised nets, and automatically learns rich hierarchical representations that are important in order to resolve the challenging ambiguity in edge and object boundary detection.
DeepLab: Semantic Image Segmentation with Deep Convolutional Nets, Atrous Convolution, and Fully Connected CRFs
This work addresses the task of semantic image segmentation with Deep Learning and proposes atrous spatial pyramid pooling (ASPP), which is proposed to robustly segment objects at multiple scales, and improves the localization of object boundaries by combining methods from DCNNs and probabilistic graphical models.
CARAFE++: Unified Content-Aware ReAssembly of FEatures
This work proposes unified Content-Aware ReAssembly of FEatures (CARAFE++), a universal, lightweight, and highly effective operator to fulfill this goal and shows great potential to serve as a strong building block for modern deep networks.
