Hello everyone,<br><br>Sorry to send this again. I will appreciate if anyone gives me a hint! Thanks!<br><br>forgive me if this is a stupid question.<br><br>the SpatialObjectToImageStatisticsCalculator generate both mean and covariance matrix of f a certain region of an image specified by a spatial object.<br><br>In the example in the itk book, both mean and covariance matrix is generated from one image and one spatialobject. My question is that from one image, how can it generate a covariance matrix? What is the column vector? <br><br>Thanks a lot!<br><br>Best Regards<br>Kurt Zhao<br><!-- footer --><br><br><br><br><br><div style="border-bottom:1px solid #999"></div><br>
