You can use regular indexing, or use mat2cell(). Both are shown in the FAQ with code examples: http://matlab.wikia.com/wiki/FAQ#How_do_I_split_an_image_into_non-overlapping_blocks.3F

Thank you for response,I am interested with way to split the image up into blocks is to use indexing for 'cameraman.tif' ,but how can I deal with each block sepearatly to extact the local features because in the demo the blocks inside for loop,please could adapt/change it for this job,and thank you very much.

I'm not sure what you're asking. Inside the loop it gives you the subimage. You can then do whatever you want with it, such as passing it to a function that does whatever you want with it, such as some custom code to extract features (like you said). What do I have to adapt/change for you? Just put in a single line to call your feature finding function.
