this lab consists of some tutorial files that will show you how to use matlab ? to view brain images and convolve with a hemodynamic response function ( hrf ) 这个实验中包含一些使用指引,告诉你如何用matlab来观看脑影像,并跟血液动态反应函数做叠积运算。
it has important value in military and civil . conventional algorithms for synthetic aperture radar uses the matched filter and convolves the data with a reference phase signal which changes with range 合成孔径雷达(sar)是二战后发展起来的一种新的雷达技术,在军事和民用方面都有重要的应用价值。
that is, vibration caused by the first part of the command signal is canceled by vibration caused by the second part of the command . input shaping is implemented by convolving a sequence of impulses, an input shaper, with any desired command 输入成型通过把参考输入信号和一系列脉冲进行卷积,得到成型输入信号,而成型输入信号作用于控制对象,其中这脉冲序列就是输入成型器。
for the first time, on the view of algorithm and experimental system, the author analyze all the factors influcing the diagnose accuracy . on the basis of these analyses, " window " and convolving function with the best accuracy are selected, at the same time, the formulas of errors are deduced 在理论分析基础上,选择了具有最佳测量精度的窗函数和卷积函数,并对算法进行了改进,提高了计算精度;对实验系统各部分对测量精度的影响也进行了定量分析。
on the basis of investigation and research about the technology of reconstruction for ict image up-to-date, this paper is devoted to develop an algorithm for image reconstruction based on wavelet theory . in this paper, time-frequency distribution for spatially varying filter was used to construct convolve-kernel by dwt, to modify convolve-back-projection algorithm 本文在国内外有关ct图像重建的研究状况基础上,根据小波分析理论,利用小波变换在时频空间的可变性,用dwt变换构造卷积核,对卷积反投影算法做了改进。
