CVB Minos - High-speed decision tree object recognition and OCR/OCV
Since its first version in 1991, CVB Minos has been continuously updated and
today it still is one of the only decision tree based pattern recognition
tools in the market using real greyscale features.
For object recognition CVB Minos uses discrete features in the grey value
range that are automatically extracted from sample images during the
training phase. CVB Minos not only detects features to differentiate
between each trained object type, but also uses negative examples in
the sample images to further secure correct detection and classification.
This provides the ability to differentiate between two similar objects and
also to deal with patterns that are mixed with varying backgrounds, for
example in OCR or security print used in bank notes or credit cards.
CVB Minos is used mainly in object recognition and alignment as well
as for optical character recognition and verification, even in tough
circumstances. The tool is able to correctly identify even characters with
overlapping extremities or partially hidden characters.
For the 2016 version of Common Vision Blox a new teaching application
called Teach Bench is included allowing easy teaching of image models
for the CVB tools Minos and Polimago.
Ideal for differentiating between similar objects even in case of rotation or scaling
Can learn consistent features and ignore features that change
Integration of negative examples in the training process
Recognition of trained objects at very high speed
Character recognition (OCR/OCV) under difficult conditions
Can be trained to complex patterns (e.g. OCR) or easy patterns
Outclasses traditional edge or blob tools regarding speed, accuracy and robustness
CVB Minos deals with patterns with varying backgrounds, for example in OCR or security print used in bank notes or credit cards
CVB Minos is an expert tool for character recognition (OCR/OCV) under difficult conditions. In this example CVB Minos is used to recognize a simple OCR code.

The programming library Common Vision Blox ist used to check barcode, expiration date as well as the fruittype.
This video shows in an easy to follow step by step explanation how to acquire
and display an image with the STEMMER IMAGING machine vision software Common
Vision Blox (CVB). This tutorial is mainly intended for beginners in CVB
