Before Cmake, please download opencv 4.80 and set the opencv lib directory as OpenCV_DIR environment variable in your computer.

Beta Version Visualization

• Initial Alignment (Week of Mar 25th)

  • Anchor-Protrusion Correspondence
    • Each protrusion is possibly matched with an anchor based on the loacation and orientation compatibility score.
  • Initial Placement
    • First position letters that have a match with protrusion.
    • Then position other letters, keeping them as evenly spaced as possible.

• Refined Alignment (Week of Mar 25th)

  • Using GA, find the best alignment that minimize the combined layout energy.
  • No control point deformation so far.

Alpha Version Visualization

• Bezier Curve Representation of English letters (Week of Mar 11th)

  • For consistency, only Bezier curve segments of degree 3 is used, including the representation of straight lines. This allows for letter deformation later.
  • Normalized all bounding area to be 160,000 (the actual width and height is consistent with the original aspect ration of each letter).
  • Libraries Used:
    • FontForge (used to generate svg file from font file)
    • svg.path (used to parse svg file in python)
    • opencv (used to visualize Bezier curve segments in C++)
    • matplotlib (used to visualize Bezier curve segments in python), not part of the actual project

• Letter Anchors (Week of Mar 18th)

  • Each letter anchor has a cutting line that is visualized through the black line.
  • Adjustments: Letter j and t looks different than the font provided in the paper, so their anchors are adjusted accordingly to be straight.

• Shape Preprocessing
