How to write each slices from volume in MATLAB into jpg format?

Hello dear may you please help for solving a problem: I have 3D Volume dataset in .niit format I read this data in MATLAB and also can show each slice from this volume....but I'm unable to write each slice in jpg /2D form How we can write each slice from volume by using imwrite in MATLAB?

You probably don't want to do that anyway, unless you use lossless jpeg2000 format. Use PNG for lossless compression

for sliceIndex = 1 : size(image3d, 3)
    thisSlice = image3d(:,:,sliceIndex);
    filename = sprintf('Slice #%d.png', sliceIndex);
    imwrite(thisSlice, filename);
end

image3d is your 3-D image array.

Hi Javaid

Hope your problem is solved. You can use imwrite instead of write

Thanks for your guidance.

how to do the same code with a set of images with a loop, and save only the first slice of each image?

@Meriem YOUss, put the code above into a loop over all files, which you can get code for in the FAQ: https://matlab.fandom.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F
