how to perform closing by reconstruction followed by opening by reconstruction

 In image processing demo(watershed segmentation) following codes were used for opening by reconstruction follwed by closing by reconstruction

 

 

Ie = imerode(I, se);
Iobr = imreconstruct(Ie, I);
figure, imshow(Iobr), title('Opening-by-reconstruction (Iobr)')
Iobrd = imdilate(Iobr, se);
Iobrcbr = imreconstruct(imcomplement(Iobrd), imcomplement(Iobr));
Iobrcbr = imcomplement(Iobrcbr);
figure, imshow(Iobrcbr), title('Opening-closing by reconstruction (Iobrcbr)')

For closing by reconstruction followed by opening by reconstruction can i follow the same sequence but interchanging imerode and imdilate positioning in above code ? ;

No, you cannot. Notice the multiple imcomplement calls after the imdilate step. These are necessary in the closing by reconstruction to make the mask and marker image fit the required inputs of imreconstruct. These imcomplement calls are not necessary for the opening by reconstruction.

 

In order to reverse the operations, you would need to take lines 4 through 6 in the code you pasted, and put them above lines 1 through 3, AND rename the variables accordingly.
