Vision-based Page Segmentation

A web page segmentation algorithm that uses both the source code and the visual presentation of a web page to divide it into hierarchical visual blocks. VIPS produces a tree structure where the root node represents the entire page and leaf nodes represent the smallest meaningful visual elements. Research indicates that the fifth level of this hierarchy best matches how users perceive page structure. VIPS is widely used in accessibility research for identifying page elements that can be reordered or removed to improve screen reader navigation.
