In this blog post I showed you how to compare two images using Python. To perform our comparison, we made use of the Mean Squared Error (MSE) and the Structural Similarity Index (SSIM) functions. While the MSE is substantially faster to compute, it has the major drawback of (1) being...

通过OpenCv 加载彩色图像时是使用的 BGR 模式。但是Matplotlib 显示图像使用的 RGB 模式。 所以如果图像是用 OpenCv 读取的, 那么彩色图像使用Matplotlib不会正确的显示.详情请参阅练习。 5|3附加资源 1.Matplotlib Plotting Styles and Features 5|4练习 1.当你尝试使用 OpenCv 加载一个彩色图像并且使用 Matplotlib ...

When your project uses both Pillow and OpenCV, create a central function that abstracts the cropping logic based on whether you’re using Pillow’scrop()or OpenCV’s slicing methods. This function can intelligently handle the conversions, reducing the risk of errors and making your codebase easie...
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。
