摘要

以神经系统为基础的疾病可被认为是导致反复发作的癫痫。脑电图(EEG)可以监测大脑的电子特征。它最常用于医疗应用。功能监测记录既可以是非线性功能,也可以是非平稳功能。本文提出了一种基于快速傅立叶级数(FFS)和基于Haar的小波变换的新方法。这些方法是用于各种癫痫发作的脑电图为基础的信号。边界的检测是通过尺度空间的表示来实现的,它也适用于基于脑电图的信号所能获得的依赖于FBSE的频谱的图像分割,也可以利用EWT的目的来获得基于窄子带的信号。这些图像分割和分类过程都是通过基于FPGA的微处理器和系统来实现的。FFS-HMT可以从希尔伯特边际谱产生子带信号,用HMS表示。HMS可用于计算脑电图信号相应的各种基于电平的振荡所产生的线长和熵特征。在这里,我们应用所选特征提取依赖于排序并行向量。利用脑电图信号,利用鲁棒随机森林对正常和癫痫参与者的特征提取进行分类。基于分类的性能评估可以在FPGA微处理器上测量不同脑电信号样本长度的分类准确率。目前的方法帮助神经科医生使用脑电图信号来区分健康人和癫痫患者。

Novel Model for Automatic Classification of the Epileptic Seizures Using Fast Fourier Series-Haar Wavelet Transform
The disorder based on neurological can be considered as epilepsy that leads to the recurrent seizures in occurrence. The electronic characteristics of brain can be monitor by the electroencephalogram (EEG). It is most commonly used in the medical application. The function monitoring records can be non linear as well as non stationary functioning. The present work produce a novel methodology, it is depend on Fast Fourier series (FFS) and wavelet transform based on Haar. These methods are used for the various kinds of epileptic seizure the electroencephalogram based signal. The detection of boundary is occur by the representation of scale-space and it also adapted to the image segmentation of the spectrum depends on the FBSE that can be obtained with the electroencephalogram based signal and the purpose of the EWT is also used to attain the narrow sub band based signals. These image segmentation and classification process implementation by FPGA based microprocessor and systems. The FFS-HMT can produce the sub band signal from the Hilbert marginal spectrum it is represented as HMS. The HMS can be used to compute the line length and the entropy characteristics due to the corresponding various kinds of the level based oscillatory of the electroencephalogram signal. Here we apply the selected feature extraction depends on the ranking parallel vector. With the use of an electroencephalogram signal, the robust random forest is utilized to classify selected feature extraction in normal and epileptic participants. The assessment of performance based on classification can be measured in FPGA microprocessor the term of classification accuracy for different sample length of EEG. The current methodology aids neurologists in distinguishing between healthy and epileptic people using electroencephalogram signals.
