Block-Run Run-Length Coding of Handwriting and Bilevel Graphics Based on Quadtree Segmentation

Yuen, H and Hanzo, L (1997) Block-Run Run-Length Coding of Handwriting and Bilevel Graphics Based on Quadtree Segmentation Pattern Recongnition Letters, 18, (2), pp. 187-191.

Record type: Article


An efficient off-line coding scheme for handwriting and bilevel graphics based on quadtree segmentation and block-run run-length coding (RLC) is presented. By segmenting a captured handwriting or graphic image into variable size blocks according to the image activity inside the blocks and run-length coding on a block-run basis, the new scheme is able to achieve higher coding efficiency than the conventional one-dimensional RLC and its bit rate is close to that of on-line dynamographical chain coding. © 1997 Elsevier Science B.V.
