<br>I'm working with a very large dataset (1000's of 2D images, size > 1024x1024 pixels, ushort RGB pixels). A large portion of these images is background.<br><br>A few routines, like saving all the 2D images into a 3D volume, fail with segfaults due to malloc errors (on OSX 10.5.8 with 24Gb RAM; using ITK 3.16.0).<br>
<br>Is there an image format that provides 'sparse' images? This implies
there are no data values for some of the image pixels (is this the same
thing as transparent background?).<br>
<br>What is an optimal image format for working with this data?<br><br>Thanks in advance (TIA),<br>Darren<br><br>
