how we can represent an image in graph in matlab?

i need get the data from the images like those from the remote sensed image let me know that if there is any way in matlab to represent the image in graph

Do you mean "graph" in:

• the mathematical sense, or
• a colloquial "picture" sense?

If it is the former, the presumably some metrics of an image could be represented in a graph, but this depends on exactly what metrics you want to visualize.

If it is the latter, then the very first result I got searching a major search-engine for the term "matlab image" was for this page:

http://www.mathworks.com/help/matlab/ref/image.html

Perhaps those examples might be of interest to you.

I too, have no idea what this means. Christina, please clarify. Presumably you already know about imread() and multibandread().

Hi Christina,

Do you know that you can simply view the image in MATLAB by using

imshow('c:\mypicture.jpg')

If processing required on the image, you can read the image into MATLAB, perform the process and then view you as above

myPicData = imread('c:\mypicture.jpg')
%%process
imshow(myPicData)

Let us know what exactly you want to do, so that we can help better.
