When the program looks for static text on an image, the recognized text object need not exactly match the text value specified in the properties of the element. For example, you can specify the properties of a Static text element in such a way as to make the program consider text like “Supplier”, “Suppller”, etc. as a valid hypothesis for the expected static text “Supplier”. The Allowed errors property value is set in the element properties. This property specifies the maximum percentage of errors allowed in a word (i.e. the share of errors in the hypothesis text). If the share of errors exceeds the value specified in the property, the detected object will not be considered a valid hypothesis. The greater the number of errors, the poorer the quality of a hypothesis. Since the number of characters in the object is not known in advance and searched text can be of varying length, the hypothesis will be evaluated using either an absolute or a relative parameter. When formulating and evaluating a hypothesis, the program will use the more stringent of the two conditions, for example, if the detected object meets one criterion but not the other, the object will not be considered a valid hypothesis.

Static Text Hypothesis Properties

A formulated Static text hypothesis has the following type-specific properties (in addition to the general ones):
