METHOD OF CALCULATING RELIABILITY OF INPUT IMAGE BASED LOG-LIKELIHOOD SCORE

摘要

PURPOSE: A method for calculating reliability based on a log-likelihood score is provided to obtain the best reliability value without predicting a too big or small value which is reflected to a voice and an image. CONSTITUTION: Each voice score and each image score are normalized in the range of 0 to 1(S1200). The difference between a first voice score and a second voice score is calculated by voice reliability(S1300). The first voice score is the maximum value among the normalized voice scores. The difference between a first image score and a second image score is calculated by image reliability. The maximum value of the second voice score is limited by a critical voice score. The maximum value of the second image score is limited by a critical image score.
