2.) Overview

2.1.)Introduction

In this work, we propose a novel medical imagesegmentation architecture, calledMSRF-Net, which aims toovercome the above limitations. Our proposed MSRF-Netmaintains high-resolution representation throughout the pro-cess which is conducive to potentially achieving high spatialaccuracy. The MSRF-Net utilizes a novel dual-scale dense fusion (DSDF) block that performs dual scale feature exchangeand a sub-network that exchanges multi-scale features usingthe DSDF block. The DSDF block takes two different scaleinputs and employs a residual dense block that exchanges in-formation across different scales after each convolutional layerin their corresponding dense blocks. The densely connectednature of blocks allows relevant high- and low-level featuresto be preserved for the final segmentation map prediction. Themulti-scale information exchange in our network preservesboth high- and low-resolution feature representations, therebyproducing finer, richer, and spatially accurate segmentationmaps. The repeated multi-scale fusion helps in enhancing thehigh-resolution feature representations with the informationpropagated by low-resolution representations. Further, layersof residual networks allow redundant DSDF blocks to die out,and only the most relevant extracted features contribute to thepredicted segmentation maps.
