+        - Fffine transformation is a type of geometric transformation that preserves the straightness of lines and the parallelism of edges in an image. 
+        - **Key Characterisistics are:**
+        - **Preserves Parallelism** : If transformed image and original image parallelism between the lines are preserved
+        - **Preserves Lines** : Length of the lines are preserved
+        - **Does Not Preserve Angles** : It doesn't preserve angle and distance but sometimes angle between lines is preserved
+        - There are 5 types of affine transformations:
