Fractal Dimension for 2d images

[dommy]

Hi all,

I am new to this topic so pls bear with me whilst i catch up with everyone else.

I have 2 images of the same tree/bush blowing in the wind. I take the difference of these 2 images and a distinctive/repeating pattern emerges. I would like to know if it is possible to calculate the fractal dimension of this image. The goal is to determine whether motion caught between 2 images is a tree/bush blowing in the wind or something else based on the fractal dimension value.

I am using C#.

Any suggestions or pointer would be great.

thanks
