min edge length

Description

Specifies the minimum length, in pixels, for an edge to be ignored as possible text in OCR actions. (Or, put another way, the maximum length, plus 1, for an edge to be considered as possible text.) During the line-removal phase of OCR, any edge (horizontal or vertical only) whose length is greater than the specified value is eliminated for consideration as text.

Allowable values

Pixel value

Default value

50

Notes

  • min edge length can also be set through the dedicated set ocr setting action, as well as through the setting action.
  • For ease of use, this value can be derived with the OCR Detector Tool, which allows you to establish the optimum settings for the detection of text under difficult circumstances.
