| 摘 要： | 本文对Prewitt经典算子进行了分析,根据算法的计算规律提出了一种改进的计算方法,通过对常规算法与改进算法的计算量进行比较分析,从理论上说明了改进算法具有简洁的处理步骤,提高了处理的速度;又通过对200幅256×256影像的具体实验证明,改进算法不仅拥有与原算法相同的效果,而且,处理时间显著缩短。

| Abstract: | The method of Prewitt operator is analyzed in this paper.According to the rule of calculating,an improvement method of Prewitt is provided.Comparing the general method with the improved from theory,the improved is more simple to calculate.Other- wise,it takes more less time to process 200 images which is 256×256.The improved not only detects edges successfully,but also re- duced the time of processing. |
