SmartNails - Display and Image Dependent Thumbnails

摘要

In order to overcome poor readability of text and recognizability of image features in low resolution thumbnails, a novel image representation of compound document images - a SmartNail representation - is presented. SmartNails are replacements or supplements to traditional thumbnails for compound documents and contain cropped and scaled image and text segments. Image- and text-based analysis are merged to generate a layout for a particular display size with selected readable text and recognizable image regions. The analysis is efficiently performed by using information from document layout analysis and JPEG 2000 compressed file headers.
