An Algorithm for Threshold Based on Arithmetic Mean of Gray Value
() Abstract
This paper presents an algorithm for threshold employing gray level arithmetic mean based on relevant conception in probability theory.The method shows a good performance while aiming at binarizing result,time cost,computational complexity and applicability.It has been applied in PCB detecting system and a satisfactory result has been attained.
