<div dir="ltr"><div><div>Hi, I need your advice for a dilate filter I am using. I have cine 3d images (3d+time) loaded as a 4d matrix on itk. They are 25 phases of heart MRI images. So my matrix dimensions are 128,128,65,25. Following the "connected threshold" example, I apply a CurvatureFlowImageFilter for smoothing and then ConnectedThreshold for segmenting the heart and aorta. Then I use Binary dilate over the mask to close the holes (for example between the vessels). <br>
</div>The question is that the dilate operation takes too much time (around 6 min) and I have noticed that is single-threaded. As the structuring elemente I was using binary ball and now I changed to a FlatStructuringElement(box) to speed up (as I could read in a forum), but it takes the same time. Given that kind of image, what variation could I make to have a fast dilation? What about gpu based methods? I have noticed that the radius 8 ball is the problematic, when I try 4 or 2 pixel radius it works much faster. <br>
</div>Thank you very much.<br clear="all"><div><div><div><br>-- <br>José Ignacio Prieto<br>celular(nuevo): 94348182
