I am trying to compute the background markers of an image and in that process I am first binarizing the image by thresholding.For that I am using "imbinarize" and it is not working.I have given the description below.

Given is the code below.Also Iobrcbr is of type 512*512 uint8 and the code gives the following error-"Undefined function 'imbinarize' for input arguments of type 'uint8'."

%%Computing Background Markers

bw=imbinarize(Iobrcbr);

figure

imshow(bw), title('Thresholded opening-closing by reconstruction (bw)')

Answer 1

In Matlab there is no "imbinarize" function. If you have such funciton, copy it into the folder where you are running your script.

Answer 2

In the Image processing TB there is a function

im2bw

First of all thank you guys.Also after reading both the comments I got to know that some functions work only in latest 2016 version of matlab.Do you guys know what is the alternate command I can use for computing watershed transform? The command "watershed" works only with 2016 and I have an earlier version not the latest one.

[Massimo Zanetti]

Which version do you have? Type "ver" on your command line to get it. However watershed is supported also in earlier versions of Matlab (for example 2014).

Yeah it helped.Thanks :)
