Topology Data Analysis-based Error Detection for Semantic Image Transmission with Incremental Knowledge-based HARQ

no code implementations18 Mar 2024 Fei Ni, Rongpeng Li, Zhifeng Zhao, Honggang Zhang

In particular, different from the conventional CRC, we introduce a topological data analysis (TDA)-based error detection method, which capably digs out the inner topological and geometric information of images, so as to capture semantic information and determine the necessity for re-transmission.
