What is Qwen segmentation? A 7th grade guide

via Dev.to BeginnersSohan Lal

Labellerr AI makes this easy. Imagine teaching a computer to "cut out" objects from photos — that's segmentation . Qwen segmentation means using smart Qwen models (like Qwen-VL or Qwen2.5-VL ) to find and outline things in images. It's like giving the AI a pair of digital scissors. You can fine tune qwen 2.5 vl to make it even better for your own pictures. How does Qwen see where objects are? Qwen models look at an image and write down coordinates — like (x1,y1),(x2,y2) . Those numbers are bounding boxes . Then extra tools (like SAM) cut out the exact shape. That's qwen segmentation in action. Researchers at HKUST used this trick: they asked Qwen-VL "where is the airplane in this image?" and got a box with coordinates (343,119),(714,261) . Then they fed that box to SAM and got a perfect airplane cut-out. That's why qwen fine tuning is powerful — you teach it your own objects. Quick facts – Qwen segmentation Uses vision-language AI – it reads text prompts AND pictures Combines with Segm
