DisDet: Exploring Detectability of Backdoor Attack on Diffusion Models

no code implementations5 Feb 2024 Yang Sui, Huy Phan, Jinqi Xiao, Tianfang Zhang, Zijie Tang, Cong Shi, Yan Wang, Yingying Chen, Bo Yuan

In this paper, for the first time, we systematically explore the detectability of the poisoned noise input for the backdoored diffusion models, an important performance metric yet little explored in the existing works.

BuildSeg: A General Framework for the Segmentation of Buildings

no code implementations15 Jan 2023 Lei LI, Tianfang Zhang, Stefan Oehmcke, Fabian Gieseke, Christian Igel

Building segmentation from aerial images and 3D laser scanning (LiDAR) is a challenging task due to the diversity of backgrounds, building textures, and image quality.

Mask-FPAN: Semi-Supervised Face Parsing in the Wild With De-Occlusion and UV GAN

no code implementations18 Dec 2022 Lei LI, Tianfang Zhang, Zhongfeng Kang, Xikun Jiang

Fine-grained semantic segmentation of a person's face and head, including facial parts and head components, has progressed a great deal in recent years.

AGPCNet: Attention-Guided Pyramid Context Networks for Infrared Small Target Detection

2 code implementations5 Nov 2021 Tianfang Zhang, Siying Cao, Tian Pu, Zhenming Peng

Infrared small target detection is an important problem in many fields such as earth observation, military reconnaissance, disaster relief, and has received widespread attention recently.

Simultaneous Monitoring of Multiple People's Vital Sign Leveraging a Single Phased-MIMO Radar

no code implementations15 Oct 2021 Zhaoyi Xu, Cong Shi, Tianfang Zhang, ShuPing Li, Yichao Yuan, Chung-Tse Michael Wu, Yingying Chen, Athina Petropulu

Based on the designed TDM phased-MIMO radar, we develop a system to automatically localize multiple human subjects and estimate their vital signs.

Probabilistic feature extraction, dose statistic prediction and dose mimicking for automated radiation therapy treatment planning

no code implementations24 Feb 2021 Tianfang Zhang, Rasmus Bokrantz, Jimmy Olsson

We show that the features extracted by the variational autoencoder capture geometric information of substantial relevance to the dose statistic prediction problem and are related to dose statistics in a more regularized fashion than hand-crafted features.

A similarity-based Bayesian mixture-of-experts model

no code implementations3 Dec 2020 Tianfang Zhang, Rasmus Bokrantz, Jimmy Olsson

We present a new nonparametric mixture-of-experts model for multivariate regression problems, inspired by the probabilistic k-nearest neighbors algorithm.
