Use the Color Thresholder app to threshold on the saturation channel. See attached demo.

I have no idea. What do you get when you do this:

>> which -all checkCC
C:\Program Files\MATLAB\R2018a\toolbox\images\images\private\checkCC.m  % Private to images

I'm sorry sir.I want the image that comes out is to delete the background only and has no graphics. Can you help me?

[Image Analyst]

@Frisda Sianipar, yes. Start your own question, after you've tried the Color Thresholder on the Apps tab of the tool ribbon of course.
