So what is image stitching ? The default is `PANORAMA` (%d), '. using tifffile), read the stage coordinate from the metadata fields (or sepearte file in the Utlramicroscope), add the numpy array as dataset with an accompanying affine transformation matrix (easy to create from stage coordinates and pixel scale) using npy2bdv (or alternatively pybdv). To stitch two images together we need to apply a technique called feature-based image alignment. December 17, 2018. 1. To stitch two images together we need to apply a technique called feature-based image alignment. However, to be able to achieve higher stitching stability and quality of the final images at least being familiar with the theory is recommended.
