In this paper, we propose a two-step bit-transform-based normalized partial distortion search (TSB-NPDS) algorithm for fast motion estimation by using the characteristics of pattern similarity matching errors. Two significant bit-plane features of image block pattern extracted by a two-bit transform are used to determine the calculation order in the proposed TSB-NPDS. The experimental results indicate...
When the customer churn prediction model is built, a large number of features bring heavy burdens to the model and even decrease the accuracy. This paper is aimed to review the feature selection, to compare the algorithms from different fields and to design a framework of feature selection for customer churn prediction. Based on the framework, the author experiment on the structured module with some...
This paper makes some improvements on MFCC feature extraction and proposes a quick MFCC algorithm which is used for Real-Time Speaker Recognition System. Based on the quick MFCC algorithm, the paper uses Differential MFCC for feature extraction and Vector Quantization plus GMM model for classification to achieve a better result. It can meet the requirements of real-time system in case of the high...
