Description: 图像平滑主要是为了消除噪声。噪声并不限于人眼所能看的见的失真和变形,有些噪声只有在进行图像处理时才可以发现。图像的常见噪声主要有加性噪声、乘性噪声和量化噪声等。图像中的噪声往往和信号交织在一起,尤其是乘性噪声,如果平滑不当,就会使图像本身的细节如边界轮廓、线条等变的模糊不清,如何既平滑掉噪声有尽量保持图像细节,是图像平滑主要研究的任务。-image smoothing is mainly to eliminate noise. Noise is not confined to the human eye can see, see the distortion and deformation, and some noise only when carrying out image processing can be found. The common image noise is the main additive noise, multiplicative noise and quantization noise. Image noise and signal often intertwined, especially multiplicative noise, if improperly smooth, images will make their own profile details such as borders, such as changing lines blurred, Smoothing out how to both noise as possible image details of the image smoothing main task.

Description: FIR(Finite Impulse Response)滤波器:有限长单位冲激响应滤波器,是数字信号处理系统中最基本的元件,它可以在保证任意幅频特性的同时具有严格的线性相频特性,同时其单位抽样响应是有限长的,因而滤波器是稳定的系统。因此,FIR滤波器在通信、图像处理、模式识别等领域都有着广泛的应用。-FIR (Finite Impulse Response) filters: finite impulse response filter unit, digital signal processing system is the most basic components, it can ensure that any increase in the frequency characteristics of both a strictly linear phase frequency characteristics, while its unit sample response is finite, and therefore the system filter is stable. Therefore, FIR filters in communications, image processing, pattern recognition and other fields have a wide range of applications. Platform: |

Description: This paper presents a new algorithm to extract
the fetal ECG from an ECG recorded on the
mother’s abdomen. The algorithm consists of
two steps: first, ECG of fetus is extracted from
the original signal using a two-level wavelet
transform. We use Daubechie wavelet transform,
which is similar in shape to heart beat wave. The
resulted signal is then low-pass filtered using the
Savitzky-Golay smoothing filter to attenuate the
effect of noise. The filtered signal is considered
as the fetal ECG. The algorithm was applied on
both synthetic and real ECG signals. The results
in this paper show that the proposed algorithm
has promising performance. Platform: |
