Blame Errant Words, Not the Canvas: Defect-Aware Spatial Credit Assignment for Visual Text Generation
Sujie Hu, Huaisong Zhang, Pujing Yang +7
Recent reinforcement learning approaches have improved visual text generation, yet generated images still suffer from incorrect wording and malformed glyphs. We identify two couple…
Dynamic Bandwidth Allocation for Hybrid Event-RGB Transmission
Pujing Yang, Guangyi Zhang, Yunlong Cai +2
Event cameras asynchronously capture pixel-level intensity changes with extremely low latency. They are increasingly used in conjunction with RGB cameras for a wide range of vision…
Joint Transmission and Deblurring: A Semantic Communication Approach Using Events
Pujing Yang, Guangyi Zhang, Yunlong Cai +2
Deep learning-based joint source-channel coding (JSCC) is emerging as a promising technology for effective image transmission. However, most existing approaches focus on transmitti…
Rate-Adaptive Generative Semantic Communication Using Conditional Diffusion Models
Pujing Yang, Guangyi Zhang, Yunlong Cai
Recent advances in deep learning-based joint source-channel coding (DJSCC) have shown promise for end-to-end semantic image transmission. However, most existing schemes primarily f…
Digital Wireless Image Transmission via Distribution Matching
Pujing Yang, Guangyi Zhang, Yunlong Cai
Deep learning-based joint source-channel coding (JSCC) is emerging as a potential technology to meet the demand for effective data transmission, particularly for image transmission…
From Analog to Digital: Multi-Order Digital Joint Coding-Modulation for Semantic Communication
Guangyi Zhang, Pujing Yang, Yunlong Cai +2
Recent studies in joint source-channel coding (JSCC) have fostered a fresh paradigm in end-to-end semantic communication. Despite notable performance achievements, present initiati…
