A method for image processing is disclosed. A non-normalized cross correlation is used to produce a cross correlation matrix between a recorded image, which contains at least one captured object, and a reference image, which contains a reference object. A comparison between a plurality of regions...
Kernel如果是对称的，cross-correlation跟convolution恰好效果是一样的。如果水平垂直翻转kernel的话，convolut...

With this procedure all the image points are used to compute the upsampled cross-correlation in a very small neighborhood around its peak. This algorithm is referred to as the single-step DFT algorithm in [1]. [1] Manuel Guizar-Sicairos, Samuel T. Thurman, and James R. Fienup, ...
2-D cross-correlation or autocorrelation matrix, returned as a matrix. More About collapse all The 2-D cross-correlation of anM-by-Nmatrix,X, and aP-by-Qmatrix,H, is a matrix,C, of sizeM+P–1 byN+Q–1. Its elements are given by ...
Basic Concepts in Signal Processing Solution: If the crosscorrelation is to include all possible shifts, we need to determine what to do when a shifted signal falls outside the range of the other signal. The common approach is to add zeros to the signals so that the signals always overlap....
Fast Normalized CrossCorrelation (快速归一化互相关).pdf,This is an expanded version of a paper from Vision Interface, 1995 (reference [10]) Fast Normalized Cross-Correlation J. P. Lewis Industrial Light Magic Abstract [16, 7, 13] and recent papers suc
Although it is well known that cross correlation can be efficiently implemented in the transform domain, the normalized form of cross correlation preferred for feature matching applications does not have a simple frequency domain expression. Normalized cross correlation has been computed in the spatial ...
First, we introduce FEFN based on attention and cross-correlation. Specifically, we add position information into the Encoder and use two parallel Encoder layers to enhance the features from two branches respectively, capturing global contextual information. Then, we embed cross-correlation operation ...
