TEARS AND THEIR FRACTAL DIMENSION

Exploring the possibility's of optically determining different types of tears.

Calculating fractal dimension by using ImageJ:

To calculate the fractal dimensions, the program ImageJ together with the plugin FracLac (Fractal Dimension and Lacunarity) will be used to analyse the micrographs containing tear crystallisation's.

All the different window overlays with all data sets regarding to the fractal dimension calculation.

Results:

Quite a time and labour intensive process, but it shows that it is indeed possible to analyse tear crystallisations with the box counting methode and calculate their fractal dimension. Next up would be to process all other 29 tears, with the same settings as described above. Starting with the other 9 emotional tears to complete the set of 10 tears for this group. Each of the emotional tears has their own background story.

The p-value is .34679. The result is not significant at p < .05.

Future plans:

To continue this experiment more tear crystallisations are needed. To do this Imaginarium of Tears is looking to get support from local universities or other interested parties, that want to help and facilitate this experiment.
