function [tilteAngle,maxAreaStart,maxAreaEnd] = radonTransform(plateGray,radonDebug)
Input grayscale image
In the angle between the x axis within +-45 radon transform analysis
Seeking all the variance of perspective projection
Find the point of maximum variance, skew detection results
This way more stable than the longest line
