SubImage(HObject imageMinuend, HObject imageSubtrahend, out HObject imageSub, HTuple mult, HTuple add)
公式
x1=imageMinuend此行此列的灰度
x2=imageSubtrahend此行此列的灰度
則imageSub此行此列的灰度為;(x1-x2)*mult+add
溢出裁剪
以byte圖為例，小于0，為0；大于255，為255
源碼一
??????? private void butTemp_Click(object sender, EventArgs e)
??????? {
??????????? var img1 = WHCSHalCon.Base.CreateByteImage(new byte[] { 0 }, 1);
??????????? var img2 = WHCSHalCon.Base.CreateByteImage(new byte[] { 255 }, 1);
??????????? HObject img3;
??????????? HOperatorSet.SubImage(img2, img1, out img3, 2, 0);
??????????? byte[] b1 = WHCSHalCon.Base.ByteImageToArr(img3);
??????? }
結(jié)果為255
