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