matlab code for brain tumor detection based on multi parameter MRI image analysis

AIM AND KEY WORDS OF THIS TOPIC IS to detect the exact location of tumor without disturbing the entire image.

 (E)EDGE PARAMETER(EDGE DETECTION)
 (G)GRAY PARAMETER
 (H)LOCAL CONTRAST, WATERSHED SEGMENTATION. 
 ***BLOCK DIAGRAM IS AS SHOWN BELOW: ***
 MRI image as input --> preprocessing --> division into blocks -->
   --> E --> G --> H --> watershed segmentation --> 2D visiualization

so far i tried like this..

firstly i have read an brain tumor mri image,by using 'imtool' command observed the pixels values. now as already we are knowing from input image the location of the tumor i placed cursor at that place and observed the pixels at that place.

but i have many doubts there sir.that is how can i differ tumor located pixels from other pixels in the image and how to highlight that part only.

i don't know what to do from this step. as i am not getting that i moved to edge detection. that to i did not get properly.

i just tried this and i don't that is this is correct or not.

We need a sample picture.

[Walter Roberson]

Your question is now better written -- but we still need a sample image. Please upload one or two to some service such as imageshack and post the URL.

If you post the URL inside your question, all readers can see the images.

how can i attach or upload a file to my question?

And see this comment itself: I've embedded a link just by embedding a link. No tricks. Inside a question surrounding < and > make a link a hyperlink in addition.

[Jan]

Fine. Where have you done this? I see a link to the homepage of a university in your question, but there are not pictures.

[Jan]

Please open a new thread for this question.

can u help me to work on the code

And "If you present the code you have accomplished so far on this, and discuss the errors you have found in your code, then someone may help you to understand the errors."

But please do that in a new Question, not this one.

Answer 1

[Jan]

This request is bold. On one hand you write " I have to do", but some line later you please us to send you the code without mentioning any details about what you have done so far.

I cannot imagine, that you really expect to get a ready-made program by this way. Therefore I estimate this "question" as not serious.

EDITED: Bhargavi has inserted the necessary amount of information and improved the question substantially. Now it is obvious, that his question is serious.

[Jan]

Thank you very much for this additional information. I suggest to edit the original question and replace it by the comments for this and Walter's answer. It is much more likely, that an image processing profi will spend time for answering, if the question contains 1. the information about what you have done so far, and 2. *less* uppercase letters.

You tell us, that you have tried this. Then it is the best idea to post the code, even if it is wrong. It is always *much* easier to improve a code, then to create a new one.

Answer 2

[Walter Roberson]

That paper and building the resulting code is a complete course for at least one university. It would thus seem inappropriate to provide the entire source code on demand.

The primary author's faculty description is here; you could probably locate his email address and write and ask for the software.

[Walter Roberson]

Sorry, I do not have any experience in those topics.

When searching for additional information about the paper, I noted that you have been asking in other forums for this code since February 13th. It is unfortunate that you did not happen to try here earlier.

If you present the code you have accomplished so far on this, and discuss the errors you have found in your code, then someone may help you to understand the errors.
