Question

How to detect cross or tick marks from images and document by using c# language and emguCV library ?

Your question is a bit vague because I don't think there's a general way to detect any type of tick or cross marks in all kinds of images. However if you're talking about tick marks in forms like multiple-choice exam questions that's called Optical Mark Recognition (OMR) and there are plenty of tools for handling that such as this CodeProject article : http://www.codeproject.com/Articles/626372/Creating-and-Processing-OMR-Forms-with-LEADTOOLS

Hi I assume that you need to write to read the pixel from the image which can be crosss or something else. you can take idea on the internet like barcode reader. thanks
