was trying to read a health bar level on pubg. so when getting shot the white portion decreases and the rest become black.So first i thought by reading the number of black and white color pixel. i could measure the health.

So can somebody suggest me a technique so i can read the bar

that picture is very tiny. please provide original resolution data.

and provide multiple images that represent the situation. don’t use words if you can show.

oh and I removed those tags. they weren’t helpful.
