 Please build the "AudioValidationLib" target in CMake.
 It would generate a dynamic library for CFFI to use.

 The test case should be a python file with a class inherited from AudioTest.
 You would need to modify CWrapper.cpp to add new function wrappers for the new test case.
 The class should have a method named "run" which will be invoked by the main.py.

+$ cd ImageProcessing
+$ python -m venv EquivalenceTest.venv
+$ source EquivalenceTest.venv/bin/activate
+$ pip install pillow
+$ pip install numpy
+$ pip install sys
+$ deactivate
+```
+
+### Execution
+```
+$ source EquivalenceTest.venv/bin/activate
+$ python compareImg.py <PATH/TO/Image1> <PATH/TO/Image2>
+$ deactivate
