METHOD AND APPARATUS FOR RECOGNIZING SERIAL NUMBER OF PAPER MONEY

摘要

Provided are a method and an apparatus for recognizing a serial number of paper money. The method includes: receiving an image of paper money including a plurality of figures and a plurality of characters and extracting an image of a character sequence of a portion on which the serial number is inscribed; dividing the image of the character sequence into character images having a predetermined pixel size; allocating the character images to an area having a predetermined pixel size, converting values of quantitated pixels of the area into numerical values, and arranging the values in a series of numerical sequences to generate input data; inputting the input data into a neural network which has learnt a plurality of pieces of basic character data of each character to allow the input data to coincide with the plurality of pieces of basic character data of the each character and outputting probability values depending on a number of cases of the plurality of pieces of basic character data; and arranging the probability values output from the neural network in a descending order, selecting a case according to first basic character data having the highest probability value, sequentially arranging characters corresponding to the case, and outputting the characters as a character sequence.
