title: How to handle large images in matlab without running out of memory?
body: <p>I am creating mosaic of two images based on the region matches between them using sift descriptors. The problem is when the created mosaic's size gets too large matlab runs out of memory.
  Is there some way of stitching the images without actually loading the complete images in memory.
  If not how do other gigapixel image generation techniques work or the panorama apps.</p>
