Optical Character Recognition of Non-flat Small Documents Using Android: A Case Study
Leila M Sears, Ray R. Hashemi, Michael J. Smith · 2011
Optical Character Recognition (OCR) using Android has been received a great attention. In all these efforts a flat document is selected for OCRing and non-flat documents are ignored. Labels mounted on cylindrical surfaces such as wine bottle, pill box, cans, etc, are examples of non-flat documents. The goal of this research effort is to perform optical character recognition on a non-flat document. To be more specific, we investigate OCRing of a cylindrical pill box label. Two pictures of the label are needed for the OCRing. The methodology was applied on 30 synthesized non-flat labels and on average, the system was able to accurately recognize 92.4 % of the characters. section 4. Experimental results are discussed in section 5. Conclusion and future research are the subjects of section 6. Figure 1: An example of a flat small document.
