LAD - Light Angle Detector

Brightness Mean Algorithm

• Normal Image :
  
• Converted into black and white image
• Image with only bright pixels (white mask) :
  
• Image with only dark pixels (black mask) :
  
• In both images, the average pixel is calculated
• Output Image :
  
• In above image the Green dot indicates the white mask average pixel and the Blue dot indicates average pixel of the black mask

Warning : This algorithm doesn't work 100% of the time and sometime gives wrong angle and vector. You can calculate the angle by the slope of the vector made by two points(green and blue)
