A Research on Paper-mediated Braille Automatic Extraction Method

摘要：

The paper-mediated Braille automatic and translation method referred in this paper, capture Braille images by the digital cameras, and pre-process the Braille images, segment the Braille images by the image processing technology and then extract the Braille features by the fixed nature of Braille. This method is simple, convenient, and easy to operate, also able to extract dots online in real time The paper gives the general method of Braille extraction technology, and introduces the specific image processing approach in detail The experiments show that the method is effective and accurate for Braille extraction.
