Matrox Imaging Library (MIL) Tools
The SureDotOCR tool is uniquely designed for the specific challenge of reading dot-matrix text produced by inkjet printers and dot peen markers. Its use is straightforward—users simply need to specify the dot size and the dimension, but not the location, of the text region. The tool reads text of variable length4, at any angle, with varying contrast, and/or on an uneven background. It interprets distorted and touching characters as well as characters of varying scale. It also accepts constituent dots that are of varying size and touching each other4. The tool recognizes punctuation marks and blank spaces. It supports the creation and editing of character fonts while including pre-defined fonts. The tool automatically handles multiple lines of text where each line can utilize a different font. The ability to set user-defined constraints, overall and at specific character positions, further enhances recognition rates. The SureDotOCR tool provides greater robustness and flexibility than case-specific techniques that convert dot-matrix characters into solid ones for reading with traditional character recognition tools.
