convolution means sliding a flipped kernelhacross a signalf,while cross-correlation means sliding a kernelhacross a signalf. Here flipping of a kernel means flipping values across all axes. For example, for a 2D signal, it would mean flipping both x and...
However, nearly all machine learning and deep learning libraries use the simplifiedcross-correlationfunction (2) All this math amounts to is a sign change in how we access the coordinates of the imageI(i.e., we don’t have to “flip” the kernel relative to the input when applying cross...
HARRIS, in Handbook of Digital Signal Processing, 1987 A Discrete Linear Convolution and Correlation The expression for computing the linear convolution of the sequence h(n) of length L, denoted [h(n):L], and the sequence x(n) of arbitrary length greater than L is given by (8.21a)y(n...
