I have the task of creating a system to read 1d barcodes. So far I followed the syntax on this link:
I found a difficulty in using the Detect MSER Feature in the section determining the region of the barcode. When I enter the code as below:
[~, cc] = detectMSERFeatures(Igray);
The output of the system is like this:
Error using detectMSERFeatures
Too many output arguments.
My question is:
1.Is there another syntax that can get a cc value?
2.Is there another syntax that can determine the region of the barcode?
Note : I'm using MATLAB R2014a, so I hope I will get an answer that matches the version of MATLAB that I am using.
Thankyou.
