Compare images using PHP

image-comparator's Issues

Improve comparison results precision

Currently compareHashes function calculates the result of comparison using default division operator and php's round() function, which may produce inconsistent and inprece results. Also, the default precision for all methods is set to 1, which may also produce confusing results.

We can slightly improve this aspect by utilizing php's bcmath functions or Brick's Math php package: https://github.com/brick/math. Also it would be beneficial to change default precision from 1 to a higher number
