ABSTRACT
|
| The implementation of an efficient scheme for translation, rotation and scale invariant optical character recognition is presented in this paper. An image representation is used, which is based on appropriate clustering and transformation of the image triple-correlation domain. This representation is one-to-one related to the class of all shifted-rotated-scaled versions of the original image, as well as robust to a wide variety of additive noises. Special attention is given to binary images, which are used for Optical Character Recognition, and simulation results illustrate the performance of the proposed implementation.
