WebThis filter calculates the masked normalized cross correlation (NCC) of two images under masks using FFTs instead of spatial correlation. It is much faster than spatial correlation for reasonably large structuring elements. This filter is not equivalent to simply masking the images first and then correlating them; the latter approach yields ... Web1 jan. 2024 · 2. Software description. The μ DIC toolkit provides a collection of high-level functions and classes, used for importing images, generating synthetic input data, meshing, image correlation and post-processing. The API is constructed such that the functions and classes can be used as stand-alone components.
