I have used the imsegkmeans function without problem in matlab. But when I use this function in screipt of simulink for android device, error occur.
this is error message -> Function 'imsegkmeans' not supported for code generation.
I want to use this function in simulink. Is there a solution?

What you can do in Simulink is to either turn all Acceleration off, or else set Acceleration to the lowest level beyond off, and use coder.extrinsic to declare a reference to the function.
However if you are going to need to deploy the function to a device, then you will not be able to do that.

I see... thank you for your answer. I need to find another way.

I suggest you
edit images.internal.algkmeans
and look at the algorithm.
Most of it is just reshaping the image into (rows*columns) x channels, running kmeans on that, getting a label matrix out, and reshaping that label matrix to rows x columns .

You can pass the camera feed to a MATLAB Function block which may use coder.extrinsic functions that do not do codegen. Processed video can also be displayed back to device.
For this to work, Sample time needs to be set high (0.5 or 1 sec).
