Page Segmentation

The process of dividing a web page into distinct visual or structural blocks based on layout cues such as whitespace, borders, colors, and font properties. Page segmentation algorithms like Vision Based Page Segmentation (VIPS) analyze the rendered appearance of pages to identify logical content regions. This technique is important for accessibility because it enables content adaptation tools to understand page structure and reorganize it for different devices, screen readers, or alternative browsing modes, making complex layouts navigable for users with disabilities or those on small-screen devices.
