[ITK-users] Location of 4-connected voxels with a specific intensity

[Mirco Serra]

Hello Bradley,thanks again for your help. Just to make sure, you are suggesting I use use the itkGrayScaleDilateImageFilter with a binary ball structuring element of radius 1 followed by a itkThresholdImageFilter. Is that correct? How is the dilation helping find the 4-connected voxels that share the intensity property?

Many many thanks,Mirco

Hello,
I think a Grayscale dilate and then a threshold may do what you want, if you use a cross with a radius one. The dilate with take the maximum over this template.
Hope that helps.Brad

I have a 2D gray-scale image and I need to locate all the sets of 4-connected voxels that have an intensity below a certain threshold. Do you know which method may be the best in order to do so?
Many thanks in advance for your help,Mirco_____________________________________
