Font Morphing

Introduction

C++ implementation of "Automatic shape morphing for Chinese characters"[1]. Graduation Project at ICST, Peking University.

Given any two styles of fonts, automatic shape morphing technique can produce the morphing process of the two styles.

demonstration of font morphing [1]

Overview

The algorithm is composed of the following procedures:

• template construction
• correspondence finding
• shape interpolation

algorithm overview [1]

See my undergraduate thesis for more details on principles and implementations.

Installation

Dependencies required by the program are:

• OpenCV 2.3 and above
• Eigen
• Fade2D
• SGCPD [2] (provided as a sub-project)

Developed and tested on VS 2010.

Usage

usage: fontmorphing : use the test data to demonstrate the program. fontmorphing : use the user specified data to do font morphing. Options are: : source image directory. one image file per character. : target image directory. one image file per character. <char name | char list> : a character file name, or a list of character file names.

: output directory of blended character images. : 0~1 float.the morphing ratio between the two input fonts. : 'y'|'n'. Whether to display the morphing process.

See FontMorphingGUI if you want a graphical user interface.
