Method and systems are provided for recognizing characters in an original image. The images received in the system as a set of pixels representing the original image as a character skeleton and a chaincore representation thereof. A skeleton intersection points are identified using a basis for determining a cutting points in the chaincore contours compared to the cutting points are then used to define cutting lines for segleg the original image into distinct segments. The segments are analyzed with respect to their geometric properties individually and relative to adjacent to other segments for determination that select ones of the segments may be combined wherein the combination is expected to have a high probability of conformance to a likely a digit or character. Verification that the combined string is a recognizable digit or character is accomplished using a convolutional neural network digit recognizer.
