+
+* [Git](https://git-scm.com/downloads "Download Git") must be installed on your operating system.

+
+```bash
+sudo git clone https://github.com/raj-mistry-01/Computer-Vision.git
+```

+
+## What Is It (You cam also read it in .idea folder)
+Now first we should have the students's data
+We have name and roll number of the students stored in a data.csv
+We will encode the each student's name(a string) into a qrcode
+
+In main.py
+    first we will read the data.csv and make a list of name and their rollnumber
+    By cv2 , If a student is present it will give his or her code to camera , we will 
+    decode it and by decoding it we will get his or her name after that we will remove 
+    his or her name from name list
+    Which names are left in list ,simple logic they are absent
+
+
+## Avoid A Comman Mistake : 
+In ```main.py``` the path of csv should be according your ```system```
+
+### A Question In Your Mind (I know) :
+If one student has all qrcode than it can also presents his all friends , but soon this ```code``` is going to be integretad by ```Face Recognization```
+
+## Languages Used : 
+![Python](https://img.shields.io/badge/python-3670A0?style=for-the-badge&logo=python&logoColor=ffdd54)
