+Task - Face Mask Challange By Shubham Jha
+
+Problem - You are provided with some sample images along with this task. These are images extracted from a Celebrity Dataset to be used for segmentation. The task here though, is to crop the original image (named like 'xx.jpg') using it's corresponding mask provided (named like '000xx_skin.png').
+For a complete illustration see all cells below.
+
+For this task you should only use 'numpy' for the masking task. Please use standard image processing libraries like opencv, seaborn, matplotlib etc.
