Persian Printed Document Analysis and Page Segmentation

This paper presents, a hybrid method, low-resolution and high-resolution, for Persian page segmentation. In the low-resolution page segmentation, a pyramidal image structure is constructed for multiscale analysis and segments document image to a set of regions. By high-resolution page segmentation, by connected components analysis, each region is segmented to homogeneous regions and identifyi...

Methodology for Flexible and Efficient Analysis of the Performance of Page Segmentation Algorithms

This paper presents part of a new DIA performance analysis framework aimed at Layout Analysis algorithm developers. A new region-representation scheme (an interval-based description of isothetic polygons) and a corresponding comparison approach are introduced. These enable fast and accurate geometric comparison of ground-truth with results of page segmentation, improving on current evaluation m...

High Performance Custom Computing for Image Segmentation

The use of dynamic instruction architectures based on eld-programmable gate arrays (FPGAs) is described. Using this approach, an application speciic instruction based system has been designed for image segmentation which is an important stage in a computer vision system. The speciic application of interest here is texture-based page layout segmentation for document images. The complete segmenta...

Performance Analysis and Optimization of High Density Tree-Based 3D Multilevel FPGA

A novel 3D Tree-based Multilevel FPGA architecture that unifies two unidirectional programmable interconnection network is presented in this paper. In a Tree based architecture, the interconnects are arranged in a multilevel network with the logic blocks placed at different Tree levels using ButterflyFat-Tree network topology. 2D physical layout development of a Tree-based multilevel interconne...
