Matlab Imread resizes tif file -

-

so i'm using imread function in matlab , when save tiff file , open in photoshop, has white border , can't understand why. want maintain resolution 512 512 image. ideas why? , how can fix that?

here's sample code:

b = imread('w_noise1.tif');  n = 1:5,     b = medfilt2(b); end  b = filter2(fspecial('average',3),b)/255;  imshow(b)

are sure it's issue imread? i'd surprised if is.

see this link medfilt2 explains "medfilt2 pads image 0s on edges, median values points within [m n]/2 of edges might appear distorted."

edit: tried replicate problem. issue print puts white frame around image after save it. functionality, print made printing plots. if want save image, should use imwrite.
