how to add more than 2 images for brain tumor detection?

Hi, i have 4 images in separate folder. I have to add all the picture to perform for tumor detection. But i don't know how to add all the images. I just found the code to add 2 images using imadd.

This is the image that i have to add. Is there any difference method that i can use?

Addition of four images

result=image1+image2+image3+image4;

If you add all four images, the maximum scale can be a maximum number of pixels, result will be complete white image. Is that you really want this?

Using imadd function

im1=imadd(image1,image2);
im1=imadd(image3,image4);
result=imadd(im1,im2);

To make Multidimentioanl Array (3D)

result=cat(4,image1,image2,image3,image4)

Thank you sir for replying. I have tried all the method that sir stated. Is there any different method that can avoid the resulting image to become complete white image?

after i have done that addition, the result of the segmentation came out wrong. is there any suggestion to avoid that? i am so sorry for asking so many question.

Exactly, I have mentioned that

"If you add all four images, the maximum scale can be a maximum number of pixels, result will be complete white image."

"after i have done that addition, the result of the segmentation came out wrong"

How do you know that addition segments the resultant region of imterest. May be you have look for thresholding or other image segmentation algorithms to extract the ROI. If you are beginner and wish to learn, my heartfelt suggestion would be read "Image Segmentation Chapter: Digital Image Processing Book By Gonzalez". You will get much more, then practice.

No sorry, we are here to help and learn together

Good Luck

Thank you sir,and yes i am a beginner. This is my project for this semester, my lecturer has show the result for the segmentation. And that is why i said that. Thank you for your answer and suggestion sir :D i appreciate it.
