Recent works employ source codecs to enable bitrate-efficient transmission between the edge device and the cloud. However, as these approaches are typically bound to a particular type of source codec and alternative network architectures are often not explored, this results in a suboptimal rate-distortion (RD) trade-off in the low-bitrate regime. In this work, we propose two novel source codecs that \\textit{enable extremely low bitrates, while improving RD performance}. We demonstrate the effectiveness of our proposed source codecs by achieving state-of-the-art performance in distributed semantic segmentation at below 0.2 (0.03) bits per pixel, measured using the mean intersection-over-union metric on ADE20K (Cityscapes).", "url": "https://wpnews.pro/news/distributed-semantic-segmentation-with-improved-rate-distortion-trade-off", "canonical_source": "https://arxiv.org/abs/2608.28684", "published_at": "2026-09-01 04:00:00+00:00", "updated_at": "2026-09-01 04:22:39.781269+00:00", "lang": "en", "topics": ["artificial-intelligence", "machine-learning", "computer-vision"], "entities": ["arXiv", "ADE20K", "Cityscapes"], "alternates": {"html": "https://wpnews.pro/news/distributed-semantic-segmentation-with-improved-rate-distortion-trade-off", "markdown": "https://wpnews.pro/news/distributed-semantic-segmentation-with-improved-rate-distortion-trade-off.md", "text": "https://wpnews.pro/news/distributed-semantic-segmentation-with-improved-rate-distortion-trade-off.txt", "jsonld": "https://wpnews.pro/news/distributed-semantic-segmentation-with-improved-rate-distortion-trade-off.jsonld"}}
