Core.addWeighted介绍

[英]Calculates the weighted sum of two arrays.

The function addWeighted calculates the weighted sum of two arrays as follows:

dst(I)= saturate(src1(I) alpha + src2(I)* beta + gamma)*

where I is a multi-dimensional index of array elements. In case of multi-channel arrays, each channel is processed independently. The function can be replaced with a matrix expression: ``

// C++ code:

dst = src1alpha + src2beta + gamma;

Note: Saturation is not applied when the output array has the depth CV_32S. You may even get result of an incorrect sign in the case of overflow.
[中]计算两个数组的加权和。
函数addWeighted计算两个数组的加权和，如下所示：
dst（I）=饱和（src1（I）α+src2（I）β+γ）
其中I是数组元素的多维索引。对于多通道阵列，每个通道都是独立处理的。该函数可以替换为矩阵表达式：``
//C++代码：
dst=src1α+src2β+γ；
注意：当输出数组的深度为CV_32S时，不应用饱和度。在溢出的情况下，您甚至可能会得到错误符号的结果。

  Mat dosePlaneMat = new Mat();
  addWeighted(lowerPlane.getImage().toMat(), 1.0 - fractionalDistance, upperPlane.getImage().toMat(), fractionalDistance, 0.0, dosePlaneMat);

  return dosePlane;
