There is a business process which includes printing some document and signing it by a client. However, clients often forget to sign and cause a lot of problems and excess actions. It is needed to reduce number of unsigned documents, but don’t use additional alerts and messages to be more user-friendly. I was asked to solve this problem and I’ve done it. In this post I’m going to describe solution, which uses opecv+javacv. I told about this libraries in previous post.

It is a cool library for working with images. It is written for all operation systems, it has rich possibilities, it has good documentation. However, I used to work with Java, so I’ve found java wrapper for it - JavaCV
