1、对卷积的困惑 卷积这个概念,很早以前就学过,但是一直没有搞懂。教科书上通常会给出定义,给出很多性质,也会用实例和图形进行解释,但究竟为什么要这么设计,这么计算,背后的意义是什么,往往语焉不详。作为一个学物理出身的人,一个公式倘若倘若给...

The convolution formula above may look intimidating at first, but it is actually really simple! Explicitly, for the first few terms, we have: c0=a0b0c1=a0b1+a1b0c2=a0b2+a1b1+a2b0c3=a0b3+a1b2+a2b1+a3b0c_0 = a_0b_0\\ c_1 = a_0b_1+a_1b_0\\ c_2 = a_0b_2+a_1b...
2-D convolution, returned as a vector or matrix. WhenAandBare matrices, then the convolutionC = conv2(A,B)has sizesize(A)+size(B)-1. When[m,n] = size(A),p = length(u), andq = length(v), then the convolutionC = conv2(u,v,A)hasm+p-1rows andn+q-1columns. ...

Central part of the convolution of the same size asu. 'valid' Only those parts of the convolution that are computed without the zero-padded edges. Using this option,length(w)ismax(length(u)-length(v)+1,0), except whenlength(v)is zero. Iflength(v) = 0, thenlength(w) = length(u)...
