概要	Multilingual semantic segmentation is a pixel-level scene parsing approach that assigns a semantic class label to every pixel in an image while incorporating cross-lingual capabilities — enabling a single model to recognise scene-text elements, annotations, or training signals drawn from multiple languages. It combines deep encoder-decoder architectures with multilingual language representations, making it applicable to documents, street signs, natural scene images, and medical imagery across diverse linguistic contexts.	Semantic segmentation assigns a class label to every pixel in an image, producing a dense, category-annotated map of the scene. Unlike object detection, which draws bounding boxes, it delineates the exact spatial extent of each class, making it indispensable in medical imaging, autonomous driving, satellite analysis, and any task where precise region boundaries matter.
