ISO 3166-2:ZA ISO 3166-2:ZA ISO 3166-2:ZA is the entry for South Africa in ISO 3166-2, part of the ISO 3166 standard published by the International Organization for Standardization (ISO), which defines codes for the names of the principal subdivisions (e.g., provinces or states) of all countries coded in ISO 3166-1. Currently for South Africa, ISO 3166-2 codes are defined for 9 provinces. Each code consists of two parts, separated by a hyphen. The first part is , the ISO 3166-1 alpha-2 code of South Africa. The second part is two letters. Subdivision names are listed as in the ISO 3166-2 standard published
Image registration results. However, many approaches to quantifying uncertainty or estimating deformations are computationally intensive or are only applicable to limited sets of spatial transformations. Image registration has applications in remote sensing (cartography updating), and computer vision. Due to the vast range of applications to which image registration can be applied, it is impossible to develop a general method that is optimized for all uses. Medical image registration (for data of the same patient taken at different points in time such as change detection or tumor monitoring) often additionally involves "elastic" (also known as "nonrigid") registration to cope with deformation of the
