18.4.1 Creating a logo recognition definition
To create a new logo recognition definition you proceed as follows: in menu Form recognition in WebAdmin you find the item Logo recognition. When you click it you see the following:
By clicking Edit you can edit existing logo recognition definitions and by clicking Delete you can erase existing definitions. To create a new definition click New. You will see the following mask on your screen:
In the following the individual functions are described:
- Name of definition
With this field you give the definition a name. In our example it is Petermann AG.
- Logo (image)
In order that the logo may be recognized it must be stored as image file on ArchivistaBox. Fill in the file name here.
- Position of logo in mm on sheet (X) and Position of logo in mm on sheet (Y)
Imagine the form as the 4th quadrant of a Cartesian coordinate system in order that the page width constitutes the x-axis and the page height the y-axis. The origin, i.e. the point from where measurements are taken, is in the left upperhand corner where the two axes intersect. The horizontal and vertical distances of the logo from this point on the axis are the values that must be entered in these fields.
- Number of pixels
- Number of contours
- Tolerance
- Image reduction
- Maximum rotation of logo
- Rotation iteration
- Accuracy within logo recognition
As mentioned in 18 an exact definition of the area where the object is to be found is absolutely necessary. In the same vein it is utopian to assume that it is possible to scan a document without it being slightly skew. This is the reason why we must give the system some tolerance. This field contains the accuracy factor whereby '1' means 100 percent accuracy. In the illustration above you see the factor 0.7 as a workable average.
The options Number of pixels, Number of contours, Tolerance and Image reduction cannot be used yet.
After you have filled in the necessary fields you must save your settings.
