volume_change_correlation
(results, references)[source]¶ Volume change correlation.
Computes the linear correlation of change in binary object volume between the contents of the successive binary images supplied. Measured through the Pearson product-moment correlation coefficient.
Parameters: results : sequence of array_like
Ordered list of input data containing objects. Each array_like will be converted into binary: background where 0, object everywhere else.
references : sequence of array_like
Ordered list of input data containing objects. Each array_like will be converted into binary: background where 0, object everywhere else. The order must be the same as for
results
.Returns: r : float
The correlation coefficient between -1 and 1.
p : float
The two-side p value.
