Modified and written by Chulwoo Pack (chulwoo.pack@gmail.com)
This repo contains Efficient Voronoi-based Document Layout Complexity Analysis code (originally worked by K. Kise and modified by Faisal Shafait).
1. How to Install
The code has two build files:
- Makefile builds the code with the same input/output as that of
original Kise's code
- Jamfile builds the code with the color-coded input/output
conforming to the ISegmentPage interface in OCRopus
2. How to Use
(1)
(1) ./be -ddetail [path-to-file] ./data/linesegments/[linesegment-file-name] ./data/ccs/[cc-file-name]
