Processing Tiled Images
in [Matlab]

Prev: write "on the fly" into the OutputBuffer with engEvalString(...)?
Next: Warning - Texture data too large for graphics device. Fitting to max size available.
From: Vit K on 5 May 2010 17:04 Can Matlab Image Processing Toolbox functions process images structured as tile arrays , for example FlashPix or Tiled Tiff? I'm looking for some way to analyze very large, distributed tiled images using parallel computing on mutli-core HPC hardware, without conversion into single file. Note: processing individual tiles separately is not an option, because if object (feature) spans across tiles it will not be counted as same continuous object. Many thanks in advance for any thoughts on this matter. Vit

I do not follow what you mean by 'without conversion into single file'. Could you say more? It might help to outline what kind of processing you intend to do. Folks here might be able to suggest ways to break it up in a parallel fashion. Aside: (not what you asked for, but might be useful) http://www.mathworks.com/access/helpdesk/help/toolbox/images/blockproc.html lets your process individual tiles of a tiff file (by setting the block size == tiff tile size). |
