What code you tried? What error you got? You need to give more information.....what difficulty you are facing? Attach your .tif file also.

[khalil ur Rehman]

I2 = imread('Imag11.tif');

imshow (I2);

warning('off', 'Images:initSize:adjustingMag');

imfinfo('Imag12.tif');

% File size is very larage(5mb) i can change it to jpeg kindly change it into tif and than proceed

[KSSV]

Unable to read...it says the file is corrupt....

[khalil ur Rehman]

kindly download both files from this link

YOu should use fread to read the data. Read about fread. Also have a look on Tiff

https://in.mathworks.com/help/matlab/ref/tiff.read.html

s = imfinfo('Imag11.tif') ;
T = Tiff('Imag11.tif','r') ;
I = read(T);

% These errors are displaying

The files are too small to hold all of the data, at least if it is in uncompressed form. 4096 rows by 3328 columns by 2 bytes per sample should be 27262976 bytes for the data, but the first file is only about 1/3 of that at 9678057 bytes.

If the file is not corrupt then it is using an unknown compression #32765, which I do not seem to locate any reference for. A proprietary compression scheme perhaps.

[Walter Roberson]

By the way, I used fread to read in the raw data, and I manipulated it under several potential configurations. I could see that there is some structure in the data, but nothing I could come up with looked anything like an "image".
