20080308244 | CONTAMINATION DEGREE DETERMINING APPARATUS AND CONTAMINATION DEGREE DETERMINING METHOD - A contamination degree determining apparatus for paper determines a final contamination degree of paper on the basis of values of various contamination characteristics indicating the degrees of, for example, creases, wrinkles or stains obtained from the paper. Values of a plurality of contamination characteristics are input to the contamination degree determining apparatus for paper. The apparatus calculates a plurality of evaluation values from the plurality of input contamination characteristics, the contribution degree of each of the plurality of contamination characteristics, reference vectors reflecting the distribution of the plurality of contamination characteristics, and dispersion parameters reflecting the distribution of the plurality of contamination characteristics. The apparatus determines the final contamination degree of the paper on the basis of the calculated evaluation values and the weight of each of the evaluation values. | 12-18-2008 |

20090208112 | PATTERN RECOGNITION METHOD, AND STORAGE MEDIUM WHICH STORES PATTERN RECOGNITION PROGRAM - A pattern recognition method is applied to processing of causing an information processing apparatus to recognize a pattern in a plurality of steps. The information processing apparatus detects recognition candidates which can be recognition candidates of each step. The information processing apparatus expands the recognition candidates of the next step belonging to each detected recognition candidate of each step. The information processing apparatus calculates the evaluation value of each expanded recognition candidate based on an a posteriori probability on condition of all recognition processing results for a recognition candidate which has undergone recognition processing. The information processing apparatus selects recognition candidates based on the calculated evaluation value of each recognition candidate. The information processing apparatus determines a recognition result based on the selected recognition candidates. | 08-20-2009 |
