Geometric Transformations and Data Augmentation with OpenCV: Forward/Backward Mapping, Rotation, Translation, and Affine Operations

This article explains traditional image augmentation techniques focusing on geometric transformations such as translation and rotation, describes forward and backward mapping concepts, coordinate‑system conversion, matrix representations, and provides detailed C++ OpenCV examples for implementing these operations with warpAffine and getRotationMatrix2D.
