We propose a novel coplanar filter, which exploits the coplanarity of gray-level distribution of neighboring pixels, to pre-filter the document images. Experiments show that the p...
: This paper reports on the Joaquim Nabuco Project, a pioneering work in Latin America on document digitalization, enhancement, compression, indexing, retrieval and network transmi...
Ternary content addressable (TCAM) is favorable for high-speed search due to its parallel architecture and ability for searching arbitrary-length keys. However, the usage of TCAM ...
This paper presents an efficient compression-oriented segmentation algorithm for computer-generated document images. In this algorithm, a document image is represented in a block-...
We describe a segmentation method and associated file format for storing images of color documents. We separate each page of the document into three layers, containing the backgro...
