基于数字图像处理的鱼卵计数的研究

摘要

Fisheries often need for counting the fish spawns,for manual counting method of the presence of defects,roe image acquisition with the smoothing,the grayscale value,morphological expansion Corrosion,hole filling,pretreatmentadaptive threshold adjustment to obtain optimal threshold segmentation roe Find the fish spawns of contour to fish spawns,eggs are rendered pictures to find the maximum and minimum roe area,perimeter,the experimental results show that the fish spawns method has relatively good segmentation results.%为了实现在渔业中经常需要对鱼卵进行计数需求.针对人工计数方法的存在的缺陷,提出了一种基于数字图像处理的鱼卵计数方法的研究,对采集的鱼卵图片进行了平滑,灰度化,二值化,形态学的膨胀腐蚀,空洞填充的预处理,根据自适应阈值调整来获取鱼卵分割的最佳阈值.查找鱼卵图像的轮廓,来实现鱼卵的计数,绘制鱼卵的图片求出最大和最小鱼卵的面积、周长,实验结果表明这种鱼卵计数方法简单易行,具有较好的鱼卵计数效果.达到了鱼卵计数的目的.
