Overview:
This paper presents the fundamental list of criteria for evaluating any OCR (optical character recognition) software, an important element in boosting overall quality of an identification or inspection system. It emphasizes on the importance of flexibility of the OCR tool in reading different types of font attributes, and includes an image showing different font samples. Reliability of an OCR software in recognizing even low resolution or blurred images and characters is stressed as another major criterion of evaluation, illustrating examples of character degradation. The paper also highlights the importance of considering the ease-of-use and efficiency of an OCR tool for use in any machine vision application.
