Voxels Intersecting along Orthogonal Levels Attention U-Net for Intracerebral Haemorrhage Segmentation in Head CT

1 code implementation12 Aug 2022 Qinghui Liu, Bradley J MacIntosh, Till Schellhorn, Karoline Skogen, KyrreEeg Emblem, Atle Bjørnerud

We propose a novel and flexible attention based U-Net architecture referred to as "Voxels-Intersecting Along Orthogonal Levels Attention U-Net" (viola-Unet), for intracranial hemorrhage (ICH) segmentation task in the INSTANCE 2022 Data Challenge on non-contrast computed tomography (CT).

Multi-modal land cover mapping of remote sensing images using pyramid attention and gated fusion networks

1 code implementation6 Nov 2021 Qinghui Liu, Michael Kampffmeyer, Robert Jenssen, Arnt-Børre Salberg

To this end, we propose a new multi-modality network (MultiModNet) for land cover mapping of multi-modal remote sensing data based on a novel pyramid attention fusion (PAF) module and a gated fusion unit (GFU).

Self-Constructing Graph Convolutional Networks for Semantic Labeling

1 code implementation15 Mar 2020 Qinghui Liu, Michael Kampffmeyer, Robert Jenssen, Arnt-Børre Salberg

Here, we propose a novel architecture called the Self-Constructing Graph (SCG), which makes use of learnable latent variables to generate embeddings and to self-construct the underlying graphs directly from the input features without relying on manually built prior knowledge graphs.

Dense Dilated Convolutions Merging Network for Semantic Mapping of Remote Sensing Images

1 code implementation30 Aug 2019 Qinghui Liu, Michael Kampffmeyer, Robert Jenssen, Arnt-Børre Salberg

We propose a network for semantic mapping called the Dense Dilated Convolutions Merging Network (DDCM-Net) to provide a deep learning approach that can recognize multi-scale and complex shaped objects with similar color and textures, such as buildings, surfaces/roads, and trees in very high resolution remote sensing images.
