Simple and effective feature extraction for optical character recognition
J. S. Berrío Pérez, Enrique Vidal, Lourdes Sanchez · 1994
A new representation method for recognition of handwritten charcters, called LLF (Local Line Fitting), is presented. The method, based on simple geometric operations, is very efficient and yields a relatively low-dimensional and distortion invariant representation. An important feature of the approach is that no preprocessing of the input image is required. A black
