Usage

Analyzing a 3D Model

To compute the fractal dimension of a 3D surface:

from StereoFractAnalyzer import StereoFractAnalyzer

analyzer = StereoFractAnalyzer(stl_path="path/to/your/model.stl")
surface_fractal_dimension = analyzer.get_surface_fractal_dimension()
print(f"Surface fractal dimension: {surface_fractal_dimension}")

Analyzing a 2D Image

For fractal dimension analysis of a 2D binary image:

from StereoFractAnalyzer import StereoFractAnalyzer

analyzer = StereoFractAnalyzer(img_path="path/to/your/image.png")
fractal_dimension = analyzer.get_image_fractal_dimension(plot=1)
print(f"The fractal dimension of the image is: {fractal_dimension}")

Command Line Interface

StereoFractAnalyzer's CLI allows for direct terminal-based operations for both 3D and 2D analyses.

3D Model Analysis

Analyze a 3D model from an STL file:

python -m StereoFractAnalyzer --stl path/to/your/model.stl

2D Image Analysis

Calculate the fractal dimension of a 2D binary image:

python -m StereoFractAnalyzer --img path/to/your/image.png

Combined Analysis

Conduct analyses on both a 3D model and a 2D image in one command:

python -m StereoFractAnalyzer --stl path/to/your/model.stl --img path/to/your/image.png

Help and Options
