[Insight-users] Does itkBinaryThresholdFilter compress output image ?

[강민구]

Hi.
I had a itk:Image which has a 200MB volumdata in memory.
and i used the itkBinaryThresholdFilter to threshold the image(volume) then call update().
when i check the memory, there was about only 10 MB memory increment which is too small than i thought.
The original volume pixel type is 2byte short and when it is filtered, its pixel type will be changed to 1byte uchar.
In my calculation, the output image size has to be 100MB. so memory increment has to be 100MB. But it isn't
so i think the filter compress the output image data internally(for example, using RLE compressing algorithm). is it right?
