R2U-Net : Medical Image Segmentation

Introduction

In this repository, we implement the R2U-Net network with the Paddle framework. Our model achieves F1-score 0.8232 on DRIVE dataset.

• Original Paper : Recurrent Residual Convolutional NeuralNetwork based on U-Net (R2U-Net) for Medical Image Segmentation
• Dataset : DRIVE

R2U-Net

The proposed models utilize the power of U-Net, Residual Network, as well as RCNN. There are several advantages of these proposed architectures for segmentation tasks. First, a residual unit helps when training deep architecture. Second, feature accumulation with recurrent residual convolutional layers ensures better feature representation for segmentation tasks. Third, it allows us to design better U-Net architecture with same number of network parameters with better performance for medical image segmentation.
