Domain adaptive semantic segmentation of multi-annual retrogressive thaw slumps.

Under review.

In this study, we applied the DeepLab v3+ semantic segmentation model to 3m-resolution PlanetScope optical images to construct a single-temporal RTS detection model in the Beiluhe region, and applied three domain adaption methods including fine-tuning based domain adaptive segmentation, Cycle-Consistent Generative Adversarial Networks (CycleGAN) based domain adaptive segmentation, and Domain Adversarial Neural Networks (DANN) based domain adaptive segmentation respectively to improve its temporal generalization ability.

A virtual-pinhole PET device for improving contrast recovery and enhancing lesion detectability of a one-meter-long PET scanner: a simulation study.

Published in Physics in Medicine & Biology, Volume 68, Number 14, 2023

This paper presents a simulation study to demonstrate that the contrast recovery coefficients (CRC) and detectability of small lesions of a one-meter-long positron emission tomography (PET) scanner can be further enhanced by the integration of high resolution virtual-pinhole (VP) PET devices.
