Joint Signal Detection and Automatic Modulation Classification via Deep Learning

1 code implementation29 Apr 2024 Huijun Xing, Xuhui Zhang, Shuo Chang, Jinke Ren, Zixun Zhang, Jie Xu, Shuguang Cui

Different from prior works that investigate them independently, this paper studies the joint signal detection and automatic modulation classification (AMC) by considering a realistic and complex scenario, in which multiple signals with different modulation schemes coexist at different carrier frequencies.

ScribblePolyp: Scribble-Supervised Polyp Segmentation through Dual Consistency Alignment

no code implementations9 Nov 2023 Zixun Zhang, Yuncheng Jiang, Jun Wei, Hannah Cui, Zhen Li

The second branch leverages affinity propagation to refine predictions into a soft version, extending additional supervision to unlabeled pixels.

YONA: You Only Need One Adjacent Reference-frame for Accurate and Fast Video Polyp Detection

no code implementations6 Jun 2023 Yuncheng Jiang, Zixun Zhang, Ruimao Zhang, Guanbin Li, Shuguang Cui, Zhen Li

YONA fully exploits the information of one previous adjacent frame and conducts polyp detection on the current frame without multi-frame collaborations.
