[Insight-users] HessiantoObjectnessMeasureImageFilter

[Jesse Ross-Jones]

Hi,
Thanks for the quick reply.
Reading the documentation on the MultiScaleHessian, "The Hessian-based
measure is computed from the Hessian image at each scale level and the best
response is selected." Does this mean that the final image produced is the
result at only one scale producing the best response or a mixture of the
results at different scales and each pixel is takes the value from the
hessian image giving the best response?

Thank you
Jesse
