# Sight_of_Last
On this challenge, we used netcat to have the following : 
![sol1](../IMG/sol1.png)
Following by image encoded in base64.
This image looks like : 
![decod](../IMG/decod.jpg)
So according to netcat response, we need to find the minimum distance between the centers of two circles:
I make this script which run through the images, when he detects black pixel, it continue untils white pixel, then the program backs to previous pixel ( black ) and go down untils white pixel etc to form a square in the circle, I calculate middle of square to find middle of circle and did this on full images to find all circle's center.
I remove coordinate which are ~equals and point which are not black pixel
and I get the flag ! 
```textflag : tjctf{i5_th1s_c0mput3r_v1si0n?}```
program : [findcenter.py](./findcenter.py)
