WebIn 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 … WebNormalized Cross-Correlation (NCC). The results are compared to a ground-truth using the accX accuracy measure excluding occluded pixels with a mask. For the precise details of the involved formulas (matching cost, matching algorithms and accuracy measure) refer to doc/Theory.pdf .
