QR-code recognition in an image is a well-established problem in machine vision. First of all, the research object was initially developed as a tool for more “comfortable” recognition. Secondly, the problem gets broken into a few separate clear sub-tasks: QR-code localization, QR-code orientation, and QR-code decoding. It turns out that…

Today we’d like to look into the problem of post-processing the text field recognition results based on a priori knowledge about the text field. A significant part of important documents, including identification documents, consists of the fields of a different kind, such as dates, numbers, car VIN-numbers, TIN and social…

Age verification as an integral part of the industry Many countries have implemented age limits to prevent underage purchases of alcohol. Sale of products with age restrictions requires special responsibility and vigilance from trade organizations: once sell alcoholic beverages or tobacco products to minors, it can cost the seller and…

Any reasonable person today knows not to sign a document before they read it. Those who didn’t follow this simple rule might have to deal with unexpected consequences that could’ve been avoided if only they paid attention to the content of a document including the fine print. The tricks and…

Hey there, friends! As you already know, we, the Smart Engines team, specialize in text recognition (not exclusively) in various documents. Today we’d like to touch on one more challenging moment when it comes to text recognition on complex backgrounds, which is space character detection. We’ll be using names on…

Obsolete ways of entering and keeping personal data While visiting various offices/organizations and business centers with the visitor permit system sometimes it seems that you are stuck in the past: we can often watch continuously listening to the radio or watching TV guards who take the visitor’s passport and manually…

Why fake documents detection became so important Nowadays we witness the ongoing services growth which has become possible to provide remotely due to the advancement of technology, providers in some cases face the need for remote client’s identity which is vital for on-boarding, processing travel documents and implementation of customer profile. At…

It is quite hard to find a problem to be solved by any other way than a neural network. Moreover, other methods are not even considered in many cases. Logically enough during a ‘silver bullet’ hunt researchers and technologists propose newer and better neural-network architecture modifications which are supposed to…

While the global object recognition community trains tens and even hundreds of successful artificial neural network (ANN) architectures that heating up the planet with the powerful video cards and developing a “panacea” for any computer vision problem, we, the Smart Engines team, don’t veer off our research path and keep…

As we all know classification’s objective is to include any object from any selection to one or a few different categories of a number of predetermined categories. 1. Problem statement Classification algorithm can be created based on machine learning that uses a training selection of some objects that have been…
