Web15 de mai. de 2024 · Compute the 2D spatial autocorrelation of a matrix or image I using the Wiener - Khintchine Theorem. The output is the normalized correlation coefficient -1 < C < 1. The center pixel of A will have C = 1. Using images with odd dimensions will give results that are easier to interpret. See detailed examples in the m-file help. 日本語; Polski; Português ... Normalized correlation is one of the methods used for template matching, a process used for finding instances of a pattern or object within an image. It is also the 2-dimensional version of Pearson product-moment correlation coefficient. Normalized cross-correlation (NCC) Ver mais In signal processing, cross-correlation is a measure of similarity of two series as a function of the displacement of one relative to the other. This is also known as a sliding dot product or sliding inner-product. It is … Ver mais For continuous functions $${\displaystyle f}$$ and $${\displaystyle g}$$, the cross-correlation is defined as: If $${\displaystyle f}$$ and $${\displaystyle g}$$ are … Ver mais Cross-correlations are useful for determining the time delay between two signals, e.g., for determining time delays for the propagation of acoustic signals across a … Ver mais • Autocorrelation • Autocovariance • Coherence • Convolution Ver mais In time series analysis and statistics, the cross-correlation of a pair of random process is the correlation between values of the processes at different times, as a function of the two times.
