提出一种基于欧氏距离和相对距离对马铃薯绿皮进行检测的检测方法。该方法以颜色特征分析为基础,利用RGB空间特征,结合阈值选取,实现对马铃薯绿皮缺陷检测。首先建立马铃薯图像采集系统,采集绿皮马铃薯图像进行彩色图像预处理;通过利用阈值判别方法对马铃薯绿皮进行检测,实现对绿皮区域的准确分割。试验结果表明,该方法能够正确识别绿皮区域,准确率达93%,方法简单、识别率高、稳定性强。
提齣一種基于歐氏距離和相對距離對馬鈴藷綠皮進行檢測的檢測方法。該方法以顏色特徵分析為基礎,利用RGB空間特徵,結閤閾值選取,實現對馬鈴藷綠皮缺陷檢測。首先建立馬鈴藷圖像採集繫統,採集綠皮馬鈴藷圖像進行綵色圖像預處理;通過利用閾值判彆方法對馬鈴藷綠皮進行檢測,實現對綠皮區域的準確分割。試驗結果錶明,該方法能夠正確識彆綠皮區域,準確率達93%,方法簡單、識彆率高、穩定性彊。
