Near-duplicate document image matching: A graphical perspective
作者：
Highlights：
• We propose a near-duplicate document image matching approach.
• Document images are represented by graphs.
• The nodes correspond to the objects in the images.
• The edges capture the relations among the objects.
• A multi-granularity object tree is built to settle the instability of object segmentation.
