显示 更早的评论
Am making a face counter , my main problem is that whe it dosent detect a face, matlab dosent print a '0' value , on the command box just dosent apear anything unless it detects a face.
Am ussing the following code.
n= size (bbox,1);
str_n= num2str(n);
str= strcat( 'number of faces are ', str_n);
display(str);

How exactly are you detecting a face? by the number of rows of bbox?

We would probably need to see the surrounding code to see if possibly that code is not executed in that situation.
By the way, I recommend you have a look at fprintf
