viewing a file as an image..??...

Started by Khubaib December 11, 2002
Dear members..i am an electrical engg.. And doing an image processing
project. The problem is that
i want to view a Y pixels file (.Y file) as an image. So, that a
print of it can be taken..Is there any command
in matlab that can take a file ( having pixel values in it), and
produce an output image.??.. If an RGB scheme
is used in some command, the Y pixel's value is assigned to each R, G
and B for that particular pixel...( The .Y file just contains the Y
pixel values as bytes)...
regards,
Khubaib.



Dear Khubaib,

Try using "image" function.
I'm not sure whether it will solve your purpose but I
hope so.

Hi,
You can use 'imread()' to first get your image. Type help imread to see the
types supported. To plot it, imshow(). Hope it helps.

well i dont think imread would work as it reads image files of the types
supported by MATLAB. what u can do MAYBE is that first read the file in an array
using the conventional I/O functions like fread() (see help in this regard) and
then do imshow(array). remember the function imshow also supports particular
type of data like double or uint8 etc etc. i think this will solve ur problem

good luck
