I filter an imageA with a function called bpass and then I display it with imagesc to be able to save it (as .tif). ImageA is 1038*1388 pixels, my filtered image is 1038*1388 double as well, but when I save it (right click on the image, save as...), the picture I then open is 560*420 pixels. Why...?
prepreim = imread('well8 aft.tif');
preim = rgb2gray(prepreim);
im = double(preim);
b = bpass(im,1,4);
figure, colormap gray, imagesc(b);
Not to save it manually, I tried to add the line
But in this case I obtain a picture of dimension 875*656 pixels.
Thank you for your help.
