Some results

Some important developments were made this week.

One important topic is that we improved the metric i presented in the previous post.
Here is the new metric:

Main advantages of this metric:

  • Same treatment for all the tested algorithms
  • Penalizes the distance between the clusters 
  • Penalizes differences between the clusters sizes
  • The Number of clusters
Notice that the lower the Medium energy, the similar are the results presented by the algorithm (compared with the groundtruth)

So i achieved the following results:

Simple segmentation

Dietmayer segmentation


Spatial Nearest Neighbor 

 Multivariable segmentation

Well, and that's the first results of this metric.
In the Next post i will draw some conclusions.
