The fractal dimension is used in variety of engineering and especially medical fields due to its capability of quantitative characterization of images. There are different types of fractal dimensions, among which the most used is the box counting dimension, whose estimation is based on different methods and can be done through a variety of software packages available on internet. In this paper, ten open source software packages for estimation of the box-counting (and other dimensions) are analyzed, tested, compared and their advantages and disadvantages are highlighted. Few of them proved to be professional enough, reliable and consistent software tools to be used for research purposes, in medical image analysis or other scientific fields.
