+# Python script that converts Image to base64 encoding and vice versa.
+
+
+### Prerequisites
+* Required modules: 
+ ```base64```,  ```PIL```, ```skimage``` and ```cv2```
+* The ```base64``` is an inbuilt module.
+* Install ```PIL``` by running ```pip install Pillow```.
+* Install ```skimage``` by running ```pip install scikit-image```.
+* Install OpenCV by running ```pip install opencv-python```.
+
+
+### How to run the script
+First you need to go to the ImageStr_ViceVersa directory.
+
+```cd Scripts/Miscellaneous/ImageStr_ViceVersa```
+* Select the image from your PC by providing its path to ```im_path``` variable.
+
+And then run the following command once you are in project directory.
+
+```python3 ImageStr_ViceVersa.py```
