Fig. 6.66 An example of false recognition of an element due to non-uniqueness of a vector image:
selected element of the recognition library (a); result of incorrect recognition (b)

recognizing a small element
in a larger one
– Creation of an internal library based on the recognized part of the working project;
– Setting all necessary program parameters (parameter settings determine accuracy,
rate, and quality of automated recognition);
– Selection of the element analysis method—based on dimensions or the specified
part of the bitmap. When analyzing elements in a part of bitmap image, it is
necessary to enter anchor points for all elements to be recognized;
