\ \end{bmatrix} $ 但是OpenCV提供了可调旋转中心的缩放旋转,这样你可以在任何你喜欢的位置旋转。修正后的变换矩阵为:$ \begin{bmatrix} å & ß & (1-å)·center.x - ß·center.y \ -ß & å & ß·center.x + (1-å)center.y \ \end{bmatrix} $其中,å = scale·cos?,...
7.1 图像加法 你可以使用OpenCv中的函数 cv2.add() 将两幅图像进行加法运算,当然也可以直接使用 numpy,如 res=img1+img。两幅图像的大小类型必 一致 或者第二个图像可以使一个简单的标量值。 注意 OpenCV 中的加法与 Numpy 的加法是有所不同的。OpenCV 的加法是一种饱和操作,而 Numpy 的加法是一种模操作。
