opening a raw file

Hi everyone ,

I am trying to open a rawfile which is supposed to be a 2048*2048 array of a 2D gray color image .

I don't know why my script ain't working .

row = 2048; 
col = 2048;

fin = fopen('dark_tint36.9512_0-0-0_Normal.raw'); 
ima = fread(fin, [col row], '*uint16'); 
fclose(fin);
imshow(fin);

I have no error messages but i only see a small white rectangle in a figure which correponds to nothing . Any help ?

Thx in advance .

As you have mentioned, the image is grey scale the max and min intensity pixel values from your image is 255 and 0 which means the data is stored in uint8 format, but you are using *uint16.

You can refer this link for precision of grey scale image

You can make use of something like below example to display the image

row=2048; 
col=2048;
fin=fopen('dark_tint36.9512_0-0-0_Normal.raw','r');
I=fread(fin,[col row],'uint8'); 
k=imshow(I);
fclose(fin)
