ContourDiff: Unpaired Image Translation with Contour-Guided Diffusion Models

no code implementations16 Mar 2024 YuWen Chen, Nicholas Konz, Hanxue Gu, Haoyu Dong, Yaqian Chen, Lin Li, Jisoo Lee, Maciej A. Mazurowski

We evaluate our method by training a segmentation model on images translated from CT to MRI with their original CT masks and testing its performance on real MRIs.

Anatomically-Controllable Medical Image Generation with Segmentation-Guided Diffusion Models

1 code implementation7 Feb 2024 Nicholas Konz, YuWen Chen, Haoyu Dong, Maciej A. Mazurowski

Diffusion models have enabled remarkably high-quality medical image generation, yet it is challenging to enforce anatomical constraints in generated images.

High Efficiency Inference Accelerating Algorithm for NOMA-based Mobile Edge Computing

no code implementations26 Dec 2023 Xin Yuan, Ning li, Tuo Zhang, Muqing Li, YuWen Chen, Jose Fernan Martinez Ortega, Song Guo

Specifically, when the mobile user has a large model inference task needed to be calculated in the NOMA-based MEC, it will take the energy consumption of both device and edge server and the inference latency into account to find the optimal model split strategy, subchannel allocation strategy (uplink and downlink), and transmission power allocation strategy (uplink and downlink).
