Notes:
These measurements
- Can be classified into four categories:
- The CooccurrenceXxx measurements are the results of the Xxx measurement for all directions.
- The CooccurrenceMeanXxx measurements are the mean of the Xxx measurement along the angular distribution.
- The CooccurrenceRangeXxx measurements are the difference between maximum and minimum of the Xxx measurement along the angular distribution.
- The CooccurrenceStddevXxx measurements are the standard deviation of the Xxx measurement along the angular distribution.
- Are customizable with the Cooccurrence attributes (for instance, to set co-occurrence offsets).
