Correlation vs Convolution Simply, correlation is a measure of similarity between two signals, and convolution is a measure of the effect of one signal on the other. 在图像或者信号处理领域,简单说,correlation 用来评估两个信号的相似
When the source signature is known, estimates of the impulse response can be obtained by processing signals received at sensors located in the waveguide, since the received signals are a convolution of the transmitted sequence and the impulse response. This chapter compares two approaches to ocean ...

The implementation comprised of two CUDA kernels: one was an optimized convolution kernel which mimicked the tiling pattern mentioned in Section 2.2, and the other was the weighted maximum likelihood estimates (WMLE) kernel which benefitted from the parallel reduction algorithm in [19]. Zhu et ...
A1, each spectral line has a pair of sidebands spaced at each modulating frequency or harmonic (from convolution of each line with the spectrum of the modulating function). These are not visible because the basic spectrum is white. However, when the spectrum is correlated with itself, this ...
weak feature correlation in initial spaces (marked in blue and green in Fig.1), which are built by feature extractors. Despite the excellent representational power of CNNs, these methods are also limited in modeling the global structural information due to the inherent local nature of convolution...
I saw an example here: community.intel.com/t5/Intel-oneAPI-Math-Kernel-Library/2D-convolution-using-VSL-Conv/m-p/1007237#M18992 (even the same exact example throws decimation error for me), and here is my code:"""MKL_INT xshape[2] = { 1...
The basic idea is that brain activity recorded with temporally- resolved neuroimaging can be decomposed as the convolution of the stimulus inputs and a filter. The filter, also known as "temporal response function", is usually unknown, and least- square fitted with a linear model. The quality...
The output voltage, vo(t), due to the signal sr(t) is given by its convolution with h(t) as in Equation 19.35. (19.35)vo(t)=∫0tsr(τ)sr(t−T−τ)dτ Since this integral is zero outside the interval for which sr(t) and sr(t − T − τ) exist, Equation 19.35 corr...
然而,在一些病态区域生成高质量的视差图时依旧存在很多问题。为了解决这个问题,我们提出了一种新型的两级CNN结构。第一级是在DispNet网络的基础上增加额外的上卷积模块(up-convolution modules),以获得保留更多细节的视差图。第二级是对第... 论文阅读《Cascade Residual Learning: A Two-stage Convolutional Neural ...
