One easy way is to write a code for that ! (assumption: there is no dot (.) in the name of the image)
IMPORTANT NOTE : if you are using Windows, you have to change '/' to '\'.
[filename, user_canceled] = imgetfile;
if user_canceled==0
L = filename=='/';
m = find(L==1,1,'last');
L = filename=='.';
n = find(L==1,1,'last');
str = filename(m+1:n-1)
end

You can use the following code to make sure it works for Windows or other OSs :
[filename, user_canceled] = imgetfile;
if user_canceled==0
if ispc
L = filename=='\';
else
L = filename=='/';
end
m = find(L==1,1,'last');
L = filename=='.';
n = find(L==1,1,'last');
str = filename(m+1:n-1)
end
