Hi Ricardo,<br><br>The image object size is only limited by the amount of<br>RAM memory in your machine, and the size of the<br>"unsigned long" in your operating system+compilation<br>mode.<br><br>This translates to:<br>
<br>1) In a Windows 64 bits machine : Max = 2Gb<br> (because unsigned long is smaller <br> than size_t in Windows)<br><br>2) In a Linux 64 bits machine: Max = your RAM<br> (given that it is likely smaller than 2^64 bytes)<br>
<br><br>The ITK streaming mechanism should help you<br>to process a very large image *as long as* you<br>are using filters that are streamable.<br><br>Examples of filters that are not streamable are<br><br>* FFT<br>* Region Growing<br>

Good day everyone,<br>
<br>
Does anyone know about the memory limits of an ITKImage object? How big can be an ITK Image object?<br>
Can the Itk streaming mechanism help me to process a very big image? Could you point me to a web page with good documentation about it?<br>
<br>
Thanks in advance,<br>
Ricardo<br>
