WebNov 11, 2024 · Correlation is a mathematical technique to see how close two things are related. In image processing terms, it is used to compute the response of a mask on an image. A mask is applied on a matrix from left to right. Mask slides over the matrix from left to right by one unit every time. WebCorrelation is another measure of the relationship between two signals. A correlation coefficient is used to evaluate similarity. If two signals have a high degree of similarity, the magnitude of the computed correlation coefficient is large.
