Question

I have an image that named ‘binary3.tiff’.

I am asked:
“In the following function (is called func) the images are given as matrices of doubles. In those images 1 represents the object and 0 (black) represents the background.”

what should the input be?
I tried:

img = imread('binary3.tiff');
img2 = double(img)/255;
newimg = func(img2);

but it doesn’t work.

please help me.

Answer 1

Without more details about what func does and the nature of the error you’re getting, I can’t help you much, but you can do this instead:

img2 = double(img > 0);

to ensure that the values in the input image are binary, and give it another go. Note that instead of 0 you can, of course, put any threshold number below which it is considered “background”.
