Calculating Fractal Dimension from Vector Images Kelly Ran
What Is A Fractal?
Fractal Dimension Lines: D=1 Squares: D=2 Fractals: Non-integer D Calculated using multiple methods Box-counting dimension
Fractal Dimension Applications Texture classification Protein molecule analysis Plant growth analysis Model: plants, particle motion
Vector Graphics Raster graphics: pixel-by-pixel Research applications calculate D from raster graphics Vector graphics: Objects like paths and shapes Scalable Vector Graphics (SVG) based on XML Paths
Goals Is it possible to calculate fractal dimension from vector images? Goals: Calculate D from SVG images Show calculations on a display screen Compare raster v. vector Time? Accuracy?
Procedures Create SVG files Inskcape Software Sierpinski Triangle, 3 iterations Sierpinski Triangle, 6 iterations
Procedures Processing language Import SVG Array of objects D calculation: size N of grid, number s of grids Hash table: N is key, s is value
Testing Line, square Fractals with known fractal dimensions
3 rd quarter development Inkscape SVGs Processing code
To Be Done Improve upon program Gather more data Implement raster method
