Efficient multi-resolution image fusion aims to take advantage of the high spectral resolution of Landsat TM images and high spatial resolution of SPOT panchromatic images simultaneously. This paper p...
Complexity versus Performance Tradeoff for Fiber Nonlinearity Compensation Using Frequency-Shaped, Multi-Subband Backpropagation
optics, fibers Nonlinear optical signal processing Wave propagation
2015/5/21
We investigate the use of an enhanced backpropagation algorithm where subbanding and frequency-shaping by pre- and post-filters are used in the calculation of nonlinearity to enable larger step sizes ...

子带特征参数在家禽应激发声识别中的应用（Application of Subband Feature of Poultry Vocalization for Identifying Their Status）
家禽 应激发声 特征提取
2009/5/19
基于子带梅尔频谱质心的优化特征参数（SMSC），研究了35日龄海兰褐蛋鸡在正常状态、光照与人为干扰等应激下发声信息的变化特征，并通过建立支持向量机模型（SVM），比较了采用优化特征参数与梅尔频标倒谱系数及其一阶、二阶导数组成的特征参数（MFCC_39）在识别不同应激中的应用效果。试验结果表明，采用加入梅尔频谱质心修正的特征参数，在分类正确识别率方面平均提高了24%。
