Compressing multi-component digital maps using JBIG2
Digital maps can be stored and, distributed electronically using compressed raster image formats. In this work, we study how the latest JBIG2 standard can be used for storing the map images. Image tiling must be performed to support direct access to partial images in the compressed file. This can be implemented by storing each image block as its own segment. Another problem is how to store the multiple image components. There are altemative ways to solve this problem by utilizing the features of JBIG2 in creative ways.
DIBCO 2009 is the first International Document Image Binarization Contest organized in the context of ICDAR 2009 conference. The general objective of the contest is to identify current advances in document image binarization using established evaluation performance measures. This paper describes the contest details including the evaluation measures used as well as the performance of the 43 submitted methods along with a short description of each method.
