The audio track of music melody includes a lot of useful information of music melody, which is the basic of music character recognition and also the premise work in the design of the performance plan of music foundation. Five eigenvectors : pitch, length, tone tempo and strength are extracted for the expression of music melody, by which, the basic music character recognition system can be set up....
High dimensional and unbalanced datasets are the main problems which prevent from achieving ideally churn prediction performance. Features selection is necessary to be adopted to enhance the model performance. A new predicting framework is proposed in this paper which uses complementary fusion of the multilayer features. Several subsets and new features were acquired according to feature factorization...
Based on electrical capacitance tomography (ECT) technology and support vector machine (SVM) algorithm, a new method for all-around identification of two-phase flow pattern is proposed combining radial information with axial information of the gas-solid two-phase flow. Compared with the conventional sectional identification method, this method adds another axial one and thus providing more information...
This paper introduces the Chinese chess recognition algorithm based on computer vision and image processing. In order to simplify processing and enhance efficiency, the images of chessboard and chessman need preprocessing in advance. The steps of preprocessing include of transformation from color images to gray images, images filtering with mean filter or median filter, and binaryzation of the gray...
Batch processes are often characterized by uneven-length durations and multistage characteristics. To reflect the inherent stage nature to improve the performances of process monitoring, simultaneously considering dynamic characteristics within the process variables for some complicated cases, stage-based variable sampling period multi-model dynamic principal component analysis (VSP-MDPCA) modeling...
The low-level line segment features have low accuracy as they are more easily affected by the noise and differeent line segment detectors. Furthermore, the line segment is not a good feature for matching across multiple views when we need to finish the 3D reconstruction. However, the line feature is more robust for the noise. In this paper, a kind of line feature, ideal line, is defined and optimally...
