Common Vision Blox - Tools
CVB has an ever expanding set of tools for all machine vision and image analysis applications. In addition to this new tools can be written using any visual programming language such as Visual C or Delphi.
The tools are grouped into the following sections ...

  Search and Read Tools

CVB Manto
         
MANTO is a neural based pattern matching tool, which opens up digital image processing to a world which is made up not only of uniform, industrially manufactured objects, standardized and illuminated with a stable light source. Using Manto enables image recognition on organic forms and textures with a high degree of deformation and poor reproducibility in an ever changing environment.

Scale and rotational invariant
Uses contours in pattern

  Measurement Tools

CVB Blob
         
This is a blob analysis tool for measuring morphometric parameters in objects of any shape which are defined by means of a binary threshold. Blob does not analyze individual pixels (pixel count, pixel statistics) but operates with a representation of contiguous object ranges in an image row - the run length code.This approach speeds up operations compared with a pixel based vision algorithm. Blob analysis is one of the most used methods to obtain statistical information about existing defects.
Software for Object Segmentation
Recognizes image sections having the same area of grey values

Returns object parameters as centroid, area, diameter etc.
CVB Edge
         
The edge tool makes use of two different techniques:
1. - Threshhold Based (binary technique)
2. - Gradient Based (greyscale)
The Gradient technique returns the position of an edge to sub pixel (1/10 pixel) accuracy. You may select white to black, black to white or all transition to be returned. The tool is optimised for speed (up to 10000 measurements per second can be achieved) The Threshold technique allows the selection of a threshold to return an edge to the nearest pixel

  Colour Processing Tools

CVB Bayer to RGB
         
Bayer to RGB converts the encoded image data from the Bayer filter output to an RGB image. Using the Bayer format, raw data from the camera can be transferred much faster than RGB images because the volume of data is much lower. However this raw data must subsequently be decoded into an RGB color format in order to be processed and displayed. The powerful CVB tool ‘Bayer To RGB’ was developed for this purpose. It supports cameras with up to 16 bit output and the converted images are in 24-bit RGB format.
Software to obtain an RGB image from cameras using Bayer mosaic filter

CVB Colour
         
Color is a color recognition tool consisting of two program modules Teach and Search. To begin with, various user-defined colors are taught to the system with Teach. The information that has been learnt is stored in a color classifier. In the second stage, the Search program can be used to search for the color in question and areas of an image can be assigned to a specific color.

  Control Tools

CVB Controls
         
The differences in functionality of cameras available on the market necessitate a new kind of software concept. In addition to the different forms of signal and channel widths covered by the frame grabber, many cameras and lighting units now also offer interfaces for the remote control of internal functions. Normally, a wide variety of functions are monitored or controlled via a serial interface. CVB control allows the control over these functions via software.
