GPS information missing in saved images ?

I have 50 Geo-tagged images in JPGE format of an area on which i am applying some function and want to save newly applied images back into JPGE format, but the saved images lack the GPS information. I need help... My code of saving images is follow...

[IN] = undistortImage(I,cameraParams,'interp','cubic');
imwrite(IN,[FolderP,'Normalized',ImFiles(i).name]);
