good meathod for pitch estimation containing examples in matlab with some explaination of different methods used as linguistic falana dhamkana.

Edge detection result should be enhanced using linear method like Median filter to remove the garbage around the pupil to gain clear pupil to determine perfect centre. Get the centre of the pupil by counting the number of black pixels (zero value) of each column and row. Then get each row and column that has the maximum number of these black pixels. Then determine the center by simple calculation according to the image coordinate to set it correct on the image, consequently we can determine the radius of the pupil. Thus we can find the pupillary boundary (inner). A similar procedure is extended by using a coarse scale to locate the outer boundary (limbus) which can be apparent by using the mid-point algorithms of circle and ellipse.

根据地震记录的统计特征和相应假设，本文采用 ARMA 模型描述地震子波，基于 高阶累积量的 ARMA 模型地震子波提取方法不仅可在压制高斯色噪声的同时保留所需 地震信号的相位信息(For the cumulant based ARMA (autoregressive moving average ) model seismic wavelet extraction method could not only retain the pahse information of the seismic wavlet while eliminating the colored Gaussian noise, but also provide a parsimonious, more efficient )

used to detect colours

Prony算法用来提取信号的幅值、频率、衰减因子和初相角。它在电力系统低频检测，谐波检测等方面运用非常广泛，但是缺点是抗噪性差，它的信号提取能力强，模拟曲线的能力强，但为了提高它的抗噪性，最好与其它方法相结合(The Prony algorithm is used to extract the amplitude, frequency, attenuation factor and initial phase angle of the signal. It is in the power system low frequency detection, harmonic detection and other aspects of the use of a very wide range, but the disadvantage is poor anti-noise, and its signal extraction ability, simulation curve ability, but in order to improve its anti-noise, the best and other methods Combine)
