what are the range of Lacunarity analysis and fractal dimension of binary images?

I want to calculate the Lacunarity value and Fractal dimension of a binary images.I used the code from below..

Lacunarity: https://www.mathworks.com/matlabcentral/fileexchange/25261-lacunarity-of-a-binary-image

Fractal dimension: https://www.mathworks.com/matlabcentral/fileexchange/30329-hausdorff--box-counting--fractal-dimension

But I cannot understand the output. I got fractal dimension >1 But for Lacunarity different types of value >1. What are the range of both the types?

I am studing fractals in my university. The range of values of fractal dimension is between 0 and 3, depending of the type image, it should value between 1 and 3. The lacunarity is more complex. give us more information, please.
