EasyOCR is a font-dependent printed character reader based on a template matching algorithm. It allows training of the font to be recognized by showing sample images of all possible characters. For this reason, it is able to read any kind of short text (serial numbers, labels...) such as those found in industrial environments. ocrsample.gif
The training phase uses an interactive utility to show samples of the characters and store them in a font file. Such a font editor is available, ready-made, in EasyAccess. Anyway, EasyOCR provides the means for you to write your own, custom, font editor.

EasyOCR provides three standard fonts: OCR-A, OCR-B and Semi. This avoids a training phase to recognize a text using one of these fonts.

  

Training

Beside the provided fonts EasyOCR can be teateach01.gifched for user defined fonts. In EasyAccess a font editor is integrated where simple training can be done by presenting an image containing the characters. Features will be extracted and stored in a configurable data base. Parameters for character separation, maximum and minimum width / height and in certain restriction for character reconstruction can be set.

Features

  • teachable fonts
  • Reconstruction of broken chars
