A very commonly used general mathemat-ical model for this distortion D: m n 7!m dis given by a polynomial distortion model [2] by neglecting any higher-order The fisheye-gs model (gsplat refer to ) is based on equiaxed projection to consider distortion processing, and the resulting effect has a relatively large projection error, especially for images with high distortion and corner areas. Go to Build Settings, and type paths in the search bar. Simple package to remove spatial distortion from images. A mustache distortion starts out as barrel distortion close to the image center and gradually turns into pincushion distortion towards the image periphery. In the context of the microtubule cytoskeleton, which is critically involved in a wide range of cellular activities, this is particularly striking, as tubulin is one of the most conserved proteins while microtubule dynamic instability is highly temperature sensitive.
