I got a satellite image of size [17935 10968] pixels,I want to cut image equally and process my required algorithm on individual parts (eg: I need to cut above pixel range into 4 equal parts).. How can I split image without loosing intermediate pixels.. My requirement is like (1 to 5600 and 5601 to the end pixel)
And anybody got any idea of handling such a huge data in Matlab..!!! (Image Size is around 600 Mb)

upperLeft = theImage(1:5600, 1:5600);
upperRight = theImage(1:5600, 5601:end);
lowerLeft = theImage(5601:end, 1:5600);
lowerLeft = theImage(5601:end, 1:5601:end);

"can you please tell how to save that blocks individually"
The variable ca is the cell array that holds all of the blocks. You can extract any one block from it using {} indexing, such as
ca{3,11}
for the third block down and 11th to the right.
You can save those in whatever way is convenient.

Depends on what you want to do once you have the 10,000 sub-images. Use either blockproc() or mat2cell().
